Accessories
Various products and tools commonly used by the stamp collector, including hinges, mounts, stamp tongs, perforation gauges, stock books and magnifiers. Stamp albums, catalogues and philatelic literature can also be regarded as accessories.
Admirals
A nickname for three British Commonwealth definitive series, those of Canada, 1912-25 (Scott 104-34); New Zealand, 1926 (182-84); and Rhodesia, 1913-19 (119-38). These stamps depict King George V in naval uniform.
Aerogramme
The official Universal Postal Union designation for an airletter sheet. These sheets, with gummed flaps, are written on and folded into themselves to form their own envelope and are carried at less than the letter airmail rate. No enclosures are permitted.
Aerophilately
A specialized area of collecting concentrating on stamps or covers carried by air.
Agency
1) An extraterritorial post office maintained at various times by a government within the territory of another government. Examples are the post offices maintained by many European powers in the Turkish Empire until 1923.
2) An organization authorized to publicize or sell new issues of stamps on behalf of a stamp-issuing entity.
Air Labels
Air labels, or etiquettes, are standard-sized blue labels used by UPU member nations to denote airmail carriage. They are inscribed "Par Avion'' (French for "By Airmail''). The text usually includes the same message in the language of the native country. Air labels also are adhesives issued by private organizations for specific, unofficial flights. See also Semi-official.
Airmail
The carriage of mail by air. The first regular airmail service began in 1870, when mail was carried from Paris-then besieged by German forces-over enemy lines by balloon. Many countries have issued postage stamps, stamped envelopes, postal cards and aerograms specially designated for airmail use. The first airmail stamp was issued by Italy in 1917 (Italy Scott C1).
Albino
An uninked impression made by a printing plate. Such errors are scarce on stamps. They are more often found on postal stationery.
Album
Albums are binders, usually with pages, for the mounting and display of stamps and covers. Albums come in many sizes, styles and themes.
Album Weed
In general, a forged stamp. It also refers to unusual items that resemble postage stamps but were not intended to pay postage, like publicity labels and bogus issues. Album Weeds is the title of a reference on forged stamps, written by the Rev. R. Brisco Earee.
Ambulante
This word means "moving" in Spanish and other Romance languages. It appears in cancellations and indicates that the item was processed by a mobile post office.
Aniline
Ink with a coal-tar base. Aniline inks are very sensitive and may dissolve in water or other liquids or chemicals. To prevent the erasure of cancellations and reuse of stamps, aniline inks were used to print some stamps.
APO
Army Post Office. An official United States post office for use by U.S. military units abroad. An army post office or military post office is set up to distribute mail to and from military personnel. Locations are indicated by numbers only to prevent revealing personnel locations. The locations become generally known after a war is over.
Approvals
Priced selections of stamps sent to collectors by mail. The collector purchases the items he chooses, returning the balance with payment for those kept.
Auction
A sale of stamps, covers and other philatelic items where prospective purchasers place bids in an attempt to obtain the desired items. The highest bidder for each lot (described item or items) makes the purchase. Auctions are generally divided into mail sales, where bids are accepted by mail, and public sales, where mail bids are combined with live bidding from individuals present at the auction or participating by telephone.
Authentication Mark
A marking, such as initials, placed on the reverse of a stamp examined and certified to be genuine by an expert. Such markings do not detract from the value of the stamps when they represent the endorsement of recognized authorities.
Back-Of-Book
Stamps that are normally listed in the back of the catalog after the regular stamp issues. This might include air mail, special delivery, semi-official, official, postage due, local issues, stamped envelopes, post cards, hunting permit stamps, essays, and revenue stamps.
Backprint
Printing on the reverse of a stamp. Some countries have printed advertising or messages on the backs of stamps.
Backstamp
A postmark applied to mail by the receiving post office or by a post office handling the piece while it is in transit. Backstamps are usually on the back of a cover, but they can be on the front.
Bank mixture
A high-quality mixture of stamps. It generally represents clippings from the mail of banks or other businesses with extensive overseas correspondence, and thus includes a relatively high proportion of foreign stamps of high face value. See also Mission mixture.
Bantams
The nickname of the South African definitive series of 1942-43 (Scott 90-97). Wartime economy measures required stamps of small size to conserve paper.
Batonne
A wove or laid paper with watermark like lines deliberately added in the papermaking process and intended as a guide for handwriting.
Bilingual
Refers to stamps inscribed in two languages. Most Canadian stamps include both English and French text. South African stamps are sometimes in both English and Afrikaans.
Bisect
A stamp cut or perforated into two parts, each half representing half the face value of the original stamp. Officially authorized bisects have often been used during temporary shortages of commonly used denominations. Unauthorized bisects appear frequently on mail from some countries in some periods. Bisects are usually collected on full cover with the stamp tied by a cancel. At times, some countries have permitted trisects or quadrisects.
Bishop Mark
The earliest postmark, introduced by Henry Bishop in England circa 1661. A Bishop Mark was used to indicate the month and day that a letter was received by a post office. It encouraged prompt delivery by letter carriers.
Blind Perforation
Perforations that have been only lightly impressed by the perforating pins, leaving the paper intact, but cut or with a faint impression. Some stamps that appear to be imperforate really are not if they have blind perfs. Stamps with blind perfs are minor varieties carrying little, if any, price premium over normally perforated copies.
Block
An un-separated grouping of four stamps forming a rectangle or square, including at least two stamps both vertically and horizontally. Most commonly a block refers to a block of four, or a block of stamps two high and two wide, though blocks often contain more stamps and may be irregularly configured.
Bluenose
The nickname for Canada Scott 158, the 50¢ issue of 1929, picturing the schooner Bluenose.
Bogus
A fictitious stamp-like label created for sale to collectors. Bogus issues include labels for nonexistent countries, nonexistent values appended to regularly issued sets and issues for nations or similar entities without postal systems.
Bond Paper
A security paper of high quality, used to a limited extent in early stamp printing. Originally, bond was made from rags. The modern paper used for first-day covers is usually a bond quality paper.
Booklet
A unit of one or more small panes or blocks (known as booklet panes) glued, stitched or stapled together between thin card covers to form a convenient unit for mailers to purchase and carry. The first officially issued booklet was produced by Luxembourg in 1895.
Bourse
A meeting of stamp collectors and/or dealers, where stamps and covers are sold or exchanged. A bourse usually has no competitive exhibits of stamps or covers. Almost all public stamp exhibitions include a dealer bourse, though many bourses are held without a corresponding exhibition.
Bull's-Eyes
1) The nickname for the first issue of Brazil, 1843 (Scott 1-3). The similar but smaller issues are called goat's eyes.
2) A bull's-eye cancel refers to a "socked-on-the-nose" cancel, one that is centered directly on the stamp so that the stamp shows the location and date of mailing.
Burelage
A design of fine, intricate lines printed on the face of security paper, either to discourage counterfeiting or to prevent the cleaning and reuse of a stamp. The burelage on some stamps is part of the stamp design.
Burele
Adjective form for burelage, meaning having a fine network of lines. Some stamps of Queens land have a burele band on the back. Also called moire.
Cachet
A design found on an envelope describing an event. Cachets appear on modern first-day covers, first-flight covers and special-event covers.
Cancel
Also known as Cancellation. A marking intended to show a stamp has been used and is no longer valid as postage. Modern cancels usually include the name of the original mailing location or a nearby sorting facility and the date of mailing. Most cancellations also include a section of lines, bars, text or a design that prints upon the postage stamp to invalidate it.
Canceled To Order
Also known as CTO. Stamps are "canceled to order," usually in full sheets, by many governments. Often, the cancels are printed on the stamps at the same time that the stamp design is printed. CTO stamps are sold to stamp dealers at large discounts from face value. CTO stamps have never seen actual postal use. Most catalogues say whether they price CTO stamps or genuinely used ones. A stamp with a cancel and with full gum is likely a CTO stamp.
Cancellation
Also known as Cancel. A marking intended to show a stamp has been used and is no longer valid as postage. Modern cancels usually include the name of the original mailing location or a nearby sorting facility and the date of mailing. Most cancellations also include a section of lines, bars, text or a design that prints upon the postage stamp to invalidate it.
Cantonal Stamps
Issues of the Swiss cantons used before the release of national stamps. The cantonal issues of Basel (1845), Geneva (1843-50) and Zurich (1843-50) are among the classics of philately.
Cape Triangles
Common name for the triangular Cape of Good Hope stamps of 1853-64, the first stamps printed in triangular format. The distinctive shape helped illiterate postal clerks distinguish letters originating in the colony from those from other colonies.
Catalogue
Comprehensive compilation of postage stamps and revenue stamps, providing descriptions and, usually, values for the items, often including stamps priced on cover.
Catalogue Value
The value of a stamp as listed in a given catalogue for the most common condition in which the stamp is usually collected. Some catalogues list stamps at a retail value. European catalogues call their retail catalogues "netto" catalogues. In general, a stamp's catalogue value should be regarded as a target price for the stamp. Some stamps are a bargain at double their catalogue value. Others may be overpriced at one quarter of their catalogue value. Most catalogues have a minimum price for the most common stamps that reflect
Censored Mail
A cover bearing a hand stamp or label indicating that the envelope has been opened and read by a censor.
Centering
The relative position of the design of a stamp in relation to its margins. Assuming that a stamp is undamaged, centering is generally a very important factor in determining condition and value.
Certified Mail
A service of most postal administrations that provides proof of mailing and delivery without indemnity for loss or damage.
Chalky paper
A chalk-surfaced paper for printing stamps. Any attempt to remove the cancel on a used chalky-paper stamp will also remove the design. Immersion of such stamps in water will cause the design to lift off. Touching chalky paper with silver will leave a discernible, pencil-like mark and is a means of distinguishing chalky paper.
Changeling
A stamp whose color has been changed-intentionally or unintentionally-by contact with a chemical or exposure to light.
Charity seals
Stamp like labels that are distributed by a charity. They have no postal validity, although they are often affixed to envelopes. United States Christmas seals are one example.
Charity stamp
Also know as semi-postal. A stamp sold at a price greater than postal value, with the additional charge dedicated for a special purpose. Usually recognized by the presence of two (often different) values, separated by a "+'' sign, on a single stamp.
Cinderella
A stamp like label that is not a postage stamp. Cinderella's include seals and bogus issues, as well as revenue stamps, local post issues and other similar items.
Classic
An early issue, often with a connotation of rarity, although classic stamps are not necessarily rare. A particularly scarce recent item may be referred to as a modern classic.
Cleaning (stamps)
Soiled or stained stamps are sometimes cleaned with chemicals or by erasing. The cleaning is usually done to improve the appearance of a stamp. A cleaned stamp can also mean one from which a cancellation has been removed, making a used stamp appear unused.
Cliché
The individual unit consisting of the design of a single stamp, combined with others to make up the complete printing plate. Individual designs on modern one-piece printing plates are referred to as subjects.
Coil
Stamps processed in a long single row and prepared for sale in rolls, often for dispensing from stamp-vending and affixing machines. Some coils, including most U.S. coils, have a straight edge on two parallel sides and perforations on the remaining two parallel sides. Some coils are back printed with sequence or counting numbers.
Commatology
Specialized collecting of postmarks. This term was invented before World War II to describe postmark collecting. It is rarely used. Usually, collectors refer to postmark collecting or marcophily.
Commemorative
A stamp printed in a limited quantity and available for purchase for a limited time. The design may note an anniversary associated with an individual, an historic event, or a national landmark. See also Definitive.
Compound Perforations
Different gauge perforations on different sides of a single stamp.
Condition
The overall appearance and soundness of a stamp or cover. Positive condition factors include fresh full colour, full original gum on unused stamps, and so on. Damage such as creases, tears, thinned paper, short perforation teeth, toning and so on negatively affect condition.
Controlled mail
A system in which the mailer selects philatelically desirable issues for outgoing mail, arranges for a specific manner of cancellation and secures the stamps' return by the addressee. In some cases such controlled mail operations may provide rare examples of specific rate fulfillment, or other similar postal use.
Copyright block
Block of four or more United States stamps with the copyright notice marginal marking of the United States Postal Service. The copyright marking was introduced in 1978 and replaced the Mail Early marking.
Corner card
A imprinted return address, generally in the upper-left corner of an envelope, from a commercial, institutional or private source, similar to business card or letterhead imprints.
Counterfeit
Any stamp, cancellation or cover created for deception or imitation, intended to be accepted by others as genuine. A counterfeit stamp is designed to deceive postal authorities.
Cover
An envelope or piece of postal stationery, usually one that has been mailed. Folded letters that were addressed and mailed without an envelope and the wrappers from mailed parcels are also covers.
Crash cover
A cover that has been salvaged from the crash of an airplane, train, ship or other vehicle. Such covers often carry a postal marking explaining damage or delay in delivery.
Crease
A noticeable weakening of the paper of a stamp or cover, caused by its being folded or bent at some point. Creases substantially lower a stamp's value. Creases particularly affect cover values when they extend through the attached stamp or a postal marking. Stamp creases are visible in watermark fluid.
CTO
Canceled-to-order. Stamps are "canceled to order,'' usually in full sheets, by many governments. The cancels may be printed on the stamps at the same time that the stamp design is printed. A stamp with a cancel and with full gum is likely a CTO stamp, as CTO's do not see actual postal use. CTO stamps are sold to stamp dealers at large discounts from face value. Most catalogues say whether they price CTO stamps or genuinely used stamps.
Cut cancellation
A cancellation that intentionally slices into the stamp paper. Often a wedge-shaped section is cut away. On many issues, such cancellations indicate use of postage stamps as fiscals (revenues) or telegraph stamps rather than as postage. Cut cancellations were used experimentally on early United States postage stamps to prevent reuse.
Cut square
A neatly trimmed rectangular or square section from a stamped envelope that includes the imprinted postage stamp with ample margin. Collectors generally prefer to collect stationery as entire pieces rather than as cut squares. Some older stationery is available only in cut squares.
Cut-to-shape
A nonrectangular stamp or postal stationery imprint cut to the shape of the design, rather than cut square. Cut-to-shape stamps and stationery generally have lower value than those cut square. One of the world's most valuable stamps, the unique 1856 British Guiana "Penny Magenta" (Scott 13), is a cut-to-shape stamp.
Cylinder
A curved printing plate used on a modern rotary press. The plate has no seams. For United States stamps, cylinders are used to print gravure stamps. See also Sleeve.
Dead country
A former stamp-issuing entity that has ceased issuing its own stamps. Also, the old name of an active stamp-issuing entity that has changed its name, so that the old name will no longer be used on stamps.
Defect
Term used to define an alteration made to the original state of a stamp. ( Cut, thin, crease, hole, missing perforation, etc.)
Definitive
Stamp issued in a large indefinite quantity and for an indefinite period, usually several years or more. Definitive stamp designs usually do not honor a specific time-dated event.
Deltiology
Picture postcard collecting.
Denomination
The face value of a stamp, usually indicated by numerals printed as part of the design. Some Canadian stamps produced for rate changes are denominated with a letter. A numerical value is assigned when the letter stamps are issued.
Die
The original engraving of a stamp. A transfer roller is made from a die, and printing plates are made from the transfer roller. When more than one die is used in the production of an issue, distinctive varieties are often identifiable.
Die cut
A form of separation usually employed on self-adhesive stamps. During processing, an edged tool (die) completely penetrates the stamp paper on all sides of the printed stamp, making the removal of the individual stamps from the liner possible. Die cuts may be straight, shaped in wavy lines to simulate perforation teeth, or take other forms.
Directory markings
Postal indication of failed delivery attempt, stating the reason for failure. Examples are "No Such Number,'' "Address Unknown'' and "Moved.''
Double printed
A stamp color that is printed twice by error. The double print is visible by the out of registration of the colors. The same is applicable for a double surcharge.
Duck stamp
Popular name for the Canadian Migratory Bird Hunting and Conservation stamp, issued for use on hunting licenses.
Dummy stamp
Officially produced imitation stamp used to train employees or to test automatic stamp-dispensing machines. Dummy stamps are usually blank or carry special inscriptions, blocks or other distinguishing ornamentation. They are not valid for postage, nor are they intended to reach the hands of stamp collectors. Some do by favor of postal employees.
Duplex cancel
A two-part postal marking consisting of a canceller and a postmark. The canceller voids the stamp so it cannot be reused. The postmark notes the date and place of mailing.
Duplicate
An additional copy of a stamp that one already has in a collection. Beginners often consider stamps to be duplicates that really are not, because they overlook perforation, watermark or color varieties.
Embossing
The process of giving relief to paper by pressing it with a die. Embossed designs are often found on the printed stamps of postal stationery (usually envelopes and wrappers). Selected stamps of certain countries have been embossed.
Encased
A stamp inserted into a small coin-size case with a transparent front or back. Such stamps were circulated as legal coins during periods when coins were scarce.
Entire
An intact piece of postal stationery, in contrast to a cut-out of the imprinted stamp. This term is sometimes used in reference to an intact cover or folded letter.
Error
A major mistake in the production of a stamp or postal stationery item. Production errors include imperforate or imperforate-between varieties, missing or incorrect colors, and inversion or doubling of part of the design or overprint. Major errors are usually far scarcer than normal varieties of the same stamp and are highly valued by collectors.
Essay
The artwork of a proposed design for a stamp. Some essays are rendered photographically. Others are drawn in pencil or ink or are painted. Most essays are rejected. One becomes the essay for the accepted design.
Europa
The "United Europe'' theme celebrated annually on stamps of western European nations since 1956. The original Europa stamps were issued by the nations in the European coal and steel association. Today, European nations that are members of the postal and telecommunications association (CEPT) issue Europa stamps.
Expertization
The examination of a stamp or cover by an acknowledged expert to determine if it is genuine. As standard procedure, an expert or expertizing body issues a signed certificate, often with an attached photograph, attesting to the item's status.
Exploded
A stamp booklet is said to be exploded when it has been separated into its various components for purposes of display. This usually refers to booklets held together by staples. Modern glued booklets usually cannot be exploded without damaging the individual booklet panes.
Express mail
Next-day mail delivery service.
Face
The front of a stamp; the side bearing the design.
Face value
The value of a stamp as inscribed on its face. For letter-denominated stamps, the understood postal value of the stamp.
Facsimile
A reproduction of a genuine stamp or cover. Such items are usually made with no intent to deceive collectors or postal officials. Catalogue illustrations may also be considered facsimiles.
Fake
A stamp, cover or cancel that has been altered or concocted to appeal to a collector. In a broad sense, fakes include repairs, reperforations and regummed stamps, as well as painted-in cancels, bogus cancels or counterfeit markings. Sometimes entire covers are faked.
Fancy cancel
A general term to describe any pictorial or otherwise unusual obliterating postmark. More specifically, the term is used to describe elaborate handmade pictorial cancels of the 19th century, such as the Waterbury "Running Chicken" of 1869 or the many intricate geometric shapes used during that period in post offices around the country.
Fast colors
Inks resistant to fading.
FDC
First-day cover. A cover bearing a stamp tied by a cancellation showing the date of the official first day of issue of that stamp.
Field Post Office
A military postal service operating in the field, either on land or at sea. Frequently abbreviated FPO.
Find
A new discovery, usually of something that was not known to exist. It can be a single item or a hoard of stamps or covers.
First-day cover
A cover bearing a stamp tied by a cancellation showing the date of the official first day of issue of that stamp.
Fiscal
A revenue stamp or similar label denoting the payment of tax. Fiscals are ordinarily affixed to documents and canceled by pen, canceller or mutilation. Because of their similarity to postage stamps, fiscals have occasionally been used either legally or illegally to prepay postage. See also Postal fiscal, Revenues.
Flat plate
A flat metal plate used in a printing press, as opposed to a curved or cylindrical plate.
Flaw
A defect in a plate that reproduces as an identifiable variety in the stamp design.
Fleet Post Office (FPO)
An official United States post office for use by U.S. military naval units abroad. Frequently abbreviated FPO.
Forerunner
A stamp or postal stationery item used in a given location prior to the issuing of regular stamps for that location. Turkish stamps before 1918 canceled in Palestine are forerunners of Israeli issues. So are the various European nations' issues for use in Palestine, and the subsequent issues of the Palestine Mandate. The term "forerunner" is also used to describe a stamp issued before another stamp or set, if the earlier issue may have influenced the design or purpose of the later issue.
Forgery
A completely fraudulent reproduction of a postage stamp. There are two general types of forgeries: those intended to defraud the postal authorities (see also Counterfeit), and those intended to defraud the collectors (see also Bogus).
FPO
See Field Post Office or Fleet Post Office.
Frama
A general name used for an automatic stamp, derived from the name of the Swiss firm, Frama AG, an early producer of such issues. Automatic stamps are produced individually by a machine on demand in a denomination selected by the customer. There normally is no date on the stamp, as there is on a meter stamp. Also called ATM, from the German word Automatenmarken.
Frame
The outer portion of a stamp design, often consisting of a line or a group of panels.
Frank
An indication on a cover that postage is prepaid, partially prepaid or that the letter is to be carried free of postage. Franks may be written, hand-stamped, imprinted or affixed. Free franking is usually limited to soldiers' mail or selected government correspondence. Postage stamp and postage meter stamps are modern methods of franking a letter.
Freak
An abnormal, usually non repetitive occurrence in the production of stamps that results in a variation from the normal stamp, but falls short of producing an error. Most paper folds, over inking and perforation shifts are freaks. Those abnormalities occurring repetitively are called varieties and may result in major errors.
Front
The front of a cover with most or all of the back and side panels torn away or removed. Fronts, while desirable if they bear unusual or uncommon postal markings, are less desirable than an intact cover.
Fugitive inks
Printing inks used in stamp production that easily fade or break up in water or chemicals. To counter attempts at forgery or the removal of cancellations, many governments have used fugitive inks to print stamps.
Ghost tagging
The appearance of a faint image impression in addition to the normal inked impression. This is caused by the miss registration of the phosphor tagging in relation to the ink. Sometimes, a plate number impression will have an entirely different number from the ink plate, giving the impression of an error: one dark (normal) number and one light (ghost) number.
Glassine
A thin, semitransparent paper that is moderately resistant to the passage of air and moisture. Envelopes made of glassine are commonly used for temporary stamp storage. Glassine is also used in the manufacture of stamp hinges.
Goldbeater's skin
A thin, tough, translucent paper. The 1886 issue of Prussia was printed in reverse on goldbeater's skin, with the gum applied over the printing. These stamps are brittle and virtually impossible to remove from the paper to which they are affixed.
Granite paper
A paper with small colored fibers added when the paper is made. This paper is used as a deterrent against forgery.
Gravure
A printing process utilizing an intaglio printing plate created by photographic and chemical means, rather than by hand engraving. See also Intaglio.
Grill
A pattern of parallel lines (or dots at the points where lines would cross) forming a grid. A grill is usually: 1) the impressed breaks added to stamps as a security measure (United States issues of 1867-71 and Peru issues of 1874-79); or 2) a grill-like canceling device used on various 19th-century issues.
Gum
The mucilage applied to the backs of adhesive postage stamps, revenue stamps or envelope flaps. Gum is an area of concern for stamp collectors. It may crack and harm the paper of the stamp itself. It may stain or adhere to other stamps or album pages under certain climatic conditions. Many collectors are willing to pay extra for 19th- and some 20th-century stamps with intact, undisturbed original gum.
Gutter
The selvage separating panes on a sheet of stamps. The gutter is usually discarded during processing. The gutter may be unprinted, or bear plate numbers, accounting or control numbers, advertising or other words or markings.
Gutter snipe
One or more stamps to which is attached the full gutter from between panes, plus any amount of an adjoining stamp or stamps. This term is typically used in reference to U.S. stamps. Gutter snipes are freaks caused by miss registration of the cutting device or paper fold over.
Hairlines
Fine lines across the face of a stamp caused by plate cracks.
Handstamp
Cancellation or overprint applied by hand to a cover or to a stamp.
Highway Post Office
(HPO) Portable mail-handling equipment for sorting mail in transit on highways (normally by truck). The last official U.S. HPO ran June 30, 1974.
Hinge
Stamp hinges are small, rectangular-shaped pieces of glassine paper, usually gummed on one side. Folded with the gummed side out, the hinge is used to mount stamps. Most modern hinges are peelable. Once dry, they may be easily removed from the stamp, leaving little trace of having been applied.
Imperforate
Refers to stamps without perforations or rouletting between the individual stamps in a pane. The earliest stamps were imperforate by design, but after about 1860 most stamps were perforated. Modern imperforates are usually errors or are produced specifically for sale to stamp collectors.
Impression
Any stamped or embossed printing.
Imprimatur
Latin for "let it be printed.'' The first sheets of stamps from an approved plate, normally checked and retained in a file prior to a final directive to begin stamp production from a plate.
India paper
A thin, tough opaque printing paper of high quality used primarily for striking die proofs.
Indicium
The stamp impression of a postage meter or the imprint on postal stationery (as opposed to an adhesive stamp), indicating prepayment and postal validity. Plural: indicia.
Inscription
The letters, words and numbers that are part of a postage stamp design.
Intaglio
Italian for "in recess.'' A form of printing in which the inked image is produced by that portion of the plate sunk below the surface. Line engraving and gravure are forms of intaglio printing.
Invert
The term generally used to describe any error where one portion of the design is inverted in relation to the other portion(s). An overprint applied upside down is also an invert.
IRC
International Reply Coupon. A redeemable certificate issued by member nations of the Universal Postal Union to provide for return postage from recipients in other countries. IRC's are exchangeable for postage at a post office.
Keytype
A basic stamp design utilized for the issues of two or more postal entities, usually differing in the country name and inscription of value. Many of the earlier colonial issues of Britain, France, Spain, Germany and Portugal are keytypes.
Kiloware
A stamp mixture consisting of miscellaneous postally used stamps on envelope corner paper from various sources. Kiloware is sometimes sold by the kilogram (about 2.2 pounds).
Label
Any stamplike adhesive that is not a postage stamp or revenue stamp.
Laid paper
One of the two basic types of paper used in stamp printing. Laid paper is distinguished from wove paper by the presence of thin, parallel lines visible when the paper is held to light. The lines are usually a few millimeters apart. See also Batonne.
Letterpress
Printing done directly from the inked, raised surface of the printing plate.
Line engraving
Printing done from an intaglio plate produced from a hand-engraved die and transfer roll rather than by photographic or chemical means. See also Gravure.
Line pair
A pair of coil stamps with a printed line between them. Stamps produced on a flatbed press have a line from the guideline between panes. Stamps produced on a rotary press have a joint line from the space where ink collects between the sections of curved rotary plates.
Liner
Coated paper used as a backing for mint self-adhesive stamps. The liner allows the release of the stamp, which may then be applied with pressure to envelope paper.
Linerless
An experimental form of self-adhesive coil stamp that requires no liner. The mint stamps are rolled upon each other in a manner similar to adhesive tape. See United States Scott 3132, 3133.
Lithography
Printing from a flat surface with a design area that is ink-receptive. The area that is not to print is ink-repellent. The process is based on the principle that an oil-based design surface will attract oily ink.
Locals
Stamps valid within a limited area or within a limited postal system. Local post mail requires the addition of nationally or internationally valid stamps for further service. Locals have been produced both privately and officially.
Machin
The name given to a well-known series of British definitive stamps first issued in 1967. The design of the stamp depicts a plaster portrait of Queen Elizabeth II created by artist Arnold Machin.
Mail Early block
U.S. marginal marking block with the selvage bearing the inscription "Mail Early (in the Day).'' This first appeared on U.S. marginal selvage in 1968. It was subsequently replaced by the copyright notice. ME blocks typically consist of four or six stamps.
Makeshift booklets
U.S. stamp booklets manufactured using stamps normally issued in individual panes, packaged in generic blue cardboard covers and dispensed by vending machines.
Marcophily
Postmark collecting.
Margin

Mat
A hard rubber plate used to apply overprints on postage stamps.
Maximaphily
Maximum card collecting.
Maximum card

Meter
The mechanical or digital device that creates a valid denominated postage imprint known as a meter stamp. Postage is prepaid to the regulating postal authority. Meters were authorized by the UPU in 1920. They are used today by volume mailers to cut the cost of franking mail.
Microprinting
Extremely small letters or numbers added to the designs of selected stamps as a security feature. In most cases, 8-power magnification or greater is needed to read microprinting.
Miniature sheet
A smaller-than-normal pane of stamps issued only in that form or in addition to full panes. A miniature sheet is usually without marginal markings or text saying that the sheet was issued in conjunction with or to commemorate some event. See also Souvenir sheet.
Mint
A stamp in the same state as issued by a post office: unused, undamaged and with full original gum (if issued with gum). Over time, handling, light and atmospheric conditions may affect the mint state of stamps.
Mirror image
An offset negative or reverse impression.
Mission mixture

Multiple
An un-separated unit of stamps including at least two stamps, but fewer than the number included in a full pane.
Native paper
Crude, handmade paper produced locally, as opposed to finer, machine-made paper.

Newspaper stamps
Stamps issued specifically for the prepayment of mailing rates for newspapers, periodicals and printed matter.
Nondenominated
A stamp with no numerical inscription designating the face value. The value of some nondenominated stamps are marked by a designated letter. Others may have a service inscription that indicates the rate the stamp fulfills.

2) An overprint intended to deface a portion of the design of a stamp, such as the face of a deposed ruler.
Obsolete
A stamp no longer available from post offices, although possibly still postally valid.
Occupation issue
An issue released for use in territory occupied by a foreign power.
Off-center
A stamp design that is not centered in relation to the edges of the stamp. Generally, off-center stamps are less desirable than stamps more nearly centered in relation to the edges. Stamps that are extremely off-center may be added to collections as production freaks.
Offices abroad
At various times, many nations have maintained post offices in other countries, usually because of the unreliability of the local postal system. In China and the Turkish Empire, especially, many foreign nations maintained their own postal systems as part of their extraterritorial powers. Usually, special stationery and stamps were used by these offices. Most consisted of overprints on the regular issues of the nations maintaining the offices.
Official
Stamp or stationery issued solely for the use of government departments and officials. In many countries such items may be available to collectors in unused condition from the postal authority.
Offset
1) A printing process that transfers an inked image from a plate to a roller. The roller then applies the ink to paper.
2) The transfer of part of a stamp design or an overprint from one sheet to the back of another, before the ink has dried (also called set off). Such impressions are in reverse (see Mirror image). They are different from stamps printed on both sides.
OG
The adhesive coating on a mint or unused stamp or envelope flap applied by a postal authority or security printer, usually before the item was issued. Upon request of stamp collectors, postal authorities have at times offered to add gum to items first issued ungummed. See also Regummed.
OHMS
Abbreviation for On His (or Her) Majesty's Service. Used in perfins, overprints or franks to indicate Official use in the British Commonwealth.
Omnibus issue
An issue released by several postal entities to celebrate a common theme. Omnibus issues may or may not share a keytype design.
On paper
Stamps (usually postally used) that are affixed to portions of original envelope or wrapper. Often used to describe stamps prior to soaking.
On piece
A stamp on a portion of the original envelope or wrapper showing all or most of the cancel. Stamps on piece are usually saved that way.
Original gum
The adhesive coating on a mint or unused stamp or envelope flap applied by a postal authority or security printer, usually before the item was issued. Upon request of stamp collectors, postal authorities have at times offered to add gum to items first issued ungummed. See also Regummed.
Overprint
Any printing over the original completed design of a stamp. An overprint that changes the value of a stamp is also called a surcharge.
Oxidation
Darkening of the ink on certain stamps caused by contact with air or light. Some inks used to print stamps, especially oranges, may in time turn brown or black.
Packet
A pre-sorted selection of all-different stamps, a common and economical way to begin a general collection.
Pair
Two unseparated stamps.
Pane
The unit into which a full press sheet is divided before sale at post offices. What a post office customer may refer to as a "sheet of stamps" is more properly called a pane. Most full sheets are divided into four or more regular panes or many more booklet panes before they are shipped to post offices.
Paquebot
Cancellation indicating an item was mailed aboard a ship.
Par Avion
A French phrase meaning "By Air,'' it appears on airmail etiquettes of most countries, along with a similar phrase in the predominant language of the country of origin.

A strong, thin paper occasionally used in stamp printing. Pelure paper is translucent and resembles a slightly dark, thin onion-skin paper.
Pen canceled
Stamps canceled with an ink pen or marker pen rather than a hand stamp or machine cancel. Many early stamps were routinely canceled by pen. A pen cancel may also indicate that a stamp was used as a fiscal. Modern stamps may be pen canceled if a sorting clerk or delivery carrier notices a stamp has been missed by a canceling machine.
Penny Black
The black 1-penny British stamp issued May 6, 1840, bearing the portrait of Queen Victoria. It is the world's first adhesive stamp issued for the prepayment of postage.
Perfins
Stamps perforated through the face with identifying initials, designs or holes in coded positions. Perfins are normally used by a business or government office to discourage pilferage or misuse of stamps by employees. Perfins may be either privately or officially produced.
Perforation
The punching out of holes between stamps to make separation easy. 1) Comb perforation-three sides of a stamp are perforated at once, with the process repeated in rows.
2) Harrow perforation-the entire sheet or unit of stamps is perforated in one operation.
3) Line perforation-holes are punched one row at a time. Line perforations are distinguished by the uneven crossing of perforation lines and irregular corners. Comb and harrow perforations usually show alignment of holes at the corners. Some forms of perforation may be difficult to distinguish.
Perforation gauge
A scale printed or designed on metal, transparent or opaque plastic, cardboard or other material to measure the number of perforation holes or teeth within the space of 2 centimeters.
Permit
Franking by the imprint of a number and additional information that identifies a mailer's prepaid postage account, thereby eliminating the need to affix and cancel stamps on large mailings. The mailer must obtain a document (permit) that authorizes his use of this procedure.
Phantom philately
The collection of bogus stamps. The name is derived from Frederick Melville's book Phantom Philately, one of the pioneer works on bogus issues.
Philatelic cover
An envelope, postal card or other item franked and mailed by a stamp collector to create a collectible object. It may or may not have carried a personal or business message. A non philatelic cover is usually one that has carried business or personal correspondence and has had its stamps applied by a non collector. Some stamps are known only on collector-created covers. It is impossible to say whether some covers are philatelically inspired or not. See also Used and Postally used.
Philately
The collection and study of postage stamps, postal stationery and postal history.
Phosphor
A chemical substance used in the production of selected stamps to activate machines that automatically cancel mail. The machines react to the phosphor under ultraviolet light. In 1959, Great Britain began to print phosphor lines on some of its stamps. See also Tagging.
Photogravure
A modern stamp-printing process that is a form of intaglio printing. Plates are made photographically and chemically, rather than by hand engraving a die and transferring it to a plate. The ink in this process rests in the design depressions. The surface of the printing plate is wiped clean. The paper is forced into the depressions and picks up the ink, in a manner much like the line-engraved printing process.
Pictorial
Stamp bearing a picture of some sort, other than a portrait or coat of arms.
Plate
The basic printing unit on a press used to produce stamps. Early stamps were printed from flat plates. Curved or cylindrical plates are used for most modern stamps. See also Cylinder and Sleeve.
Plate block
A block of stamps from the corner or side of a pane including the selvage bearing the number(s) of the plate(s) used to print the sheet from which the pane was separated. Some stamp production methods, like booklet production, normally cut off plate numbers. Plate number blocks are collected normally as blocks of four to 20 stamps, depending on the press used to print the stamps. When each stamp in a pane is a different design, the entire pane is collected as the plate block.
Plate number
Numerals or an alphanumeric combination that identifies the printing plate used to print postage stamp images. Plate numbers on sheet stamps often appear in corner margin paper or side margin paper. Plate numbers on coil stamps were commonly trimmed off until about 1980; since then the number appears on stamps at specific intervals. Booklet plate numbers are often found on selvage attached to the pane.
Plating
The reconstruction of a stamp pane by collecting blocks and individual stamps representing various positions. This is possible for many older issues, but most modern issues are too uniform to make the identification of individual positions possible.
Plebiscite issue
A stamp issue promoting a popular vote. After World War I, a number of disputed areas were placed under temporary League of Nations administration, pending plebiscites to determine which nation the populace wished to join. Special issues note the upcoming vote in several of these areas; among them, Allenstein, Carinthia, Eastern Silesia, Marienwerder, Schleswig and Upper Silesia.
PNC
1) A plate number coil stamp; that is, a stamp from a coil that is inscribed with a plate number. The abbreviations PNC3 and PNC5 identify strips of three or five coil stamps with the PNC located in the center position of the strip.
2) A philatelic-numismatic combination: a cover bearing a stamp and containing a coin, medal or token. The coin and stamp are usually related in such cases; often the cover is canceled on the first day of use of the coin.
Pneumatic post
Letter distribution through pressurized air tubes. Pneumatic posts existed in many large cities in Europe, and special stamps and stationery were often produced for the service.
Postage dues
Stamps or markings indicating that insufficient postage has been affixed to the mailing piece. Postage dues are usually affixed at the office of delivery. The additional postage is collected from the addressee.
Postal card
A government-produced postcard bearing a stamp imprint in the upper-right corner representing prepayment of postage.
Postal fiscal
Revenue or fiscal stamps used postally.
Postal history
The study of postal markings, rates and routes, or anything to do with the history of the posts.
Postal stationery
Stationery bearing imprinted stamps, as opposed to adhesive stamps. Postal stationery includes postal cards, lettercards, stamped envelopes, wrappers, aerograms, telegraph cards, postal savings forms and similar government-produced items. The cost to the mailer is often the price of postage plus an additional charge for the stationery item.
Postally used
A stamp or cover that has seen legitimate postal use, as opposed to one that has been canceled-to-order or favor-canceled. The term "postally used" suggests that an item exists because it was used to carry a personal or business communication, without the sender thinking of creating an item to be collected.
Postcard
A small card, usually with a picture on one side and a space for a written message on the other. Postcards have no imprinted stamp, so the mailer must also purchase postage to mail the postcard. See also Postal card.
Postmark
Any official postal marking. The term is usually used specifically in reference to cancellations bearing the name of a post office of origin and a mailing date.
Precancel
Stamp with a special overprint cancellation allowing it to bypass normal canceling. In some cases the precancel also designates a specific mail-handling service, such as "Presorted First-Class." Other precancels may include the city and state of the issuing post office. Precanceled stamps are used by volume mailers who hold a permit to use them
Press sheet
A complete unit of stamps as printed. Stamps are usually printed in large sheets and are separated into two or more panes before shipment to post offices.
Prestamp covers
Folded letters or their outer enclosures used before the introduction of adhesive postage stamps or postal stationery.

Printing
The process of imprinting designs on paper from an inked surface.
Pro Juventute

A stamp with an altered design as the result of a change made to a transfer roll or printing plate prior to a later printing, thereby distinguishing it from the original die.
Receiving mark
A postmark or other postal marking applied by the receiving, rather than the originating, post office. See also Backstamp.
Redrawn
A stamp design that has been slightly altered yet maintains the basic design as originally issued.
Regional

Registered mail
First-class mail with a numbered receipt, including a valuation of the registered item, for full or limited compensation if the mail is lost. Some countries have issued registered mail stamps. Registered mail is signed for by each postal employee who handles it.
Registration labels
Adhesive labels indicating the registry number and, often, the city of origin for registered articles sent through the mail.
Regummed
A stamp bearing adhesive from an unauthorized source.
Reissue
An official reprinting of a stamp from an obsolete or discontinued issue. Reissues are valid for postage. See also Reprint.
Remainders
Stocks of stamps remaining unsold at the time that an issue is declared obsolete by a post office. Some countries have sold remainders to the stamp trade at substantial discounts from face value. The countries normally mark the stamps with a distinctive cancel. Uncanceled remainders usually cannot be distinguished from stamps sold over the counter before the issue was invalidated.
Repaired stamp
A damaged stamp that has been repaired in some way to reinforce it or to make it resemble an undamaged stamp.
Replica
A reproduction of a stamp or cover. In the 19th century, replica stamps were sold as stamp album space fillers. Replica stamps are often printed in one color in a sheet containing a number of different designs. Replicas can sometimes deceive either a postal clerk or collectors.
Reprint
A stamp printed from the original plate, after the issue has ceased to be postally valid. Official reprints are sometimes made for presentation purposes or official collections. They are often distinguishable in some way from the originals: different colors, perforations, paper or gum. Private reprints, on the other hand, are usually produced strictly for sale to collectors and often closely resemble the original stamps. Private reprints normally sell for less than original copies. Reprints are not valid for postage. See also Reissue.
Retouch
The repairing of a damaged plate or die, often producing a minor, but detectable, difference in the design of the printed stamps.
Revenues
Stamps representing the prepayment or payment of various taxes. Revenues are affixed to official documents and to merchandise. Some stamps, including many issues of the British Commonwealth, are inscribed "Postage and Revenue'' and were available for either use. Such issues are usually worth less fiscally canceled than postally used. In some cases, revenues have been used provisionally as postage stamps. See also Fiscal.
Rocket mail
Mail flown in a rocket, even if only a short distance. Many rocket mail experiments have been conducted since 1931. Special labels, cachets or cancels usually note that mail was carried on a rocket.
Rotary plate
A curved or cylindrical printing plate used on a press that rotates the plate to make continuous impressions. Flat plates make single impressions.
Rouletting
The piercing of the paper between stamps to make their separation more convenient. No paper is actually removed from the sheet, as it is in perforating. Rouletting has been made by dash, sawtooth or wavy line.
Rural Free Delivery
(RFD) System for free home delivery of mail in rural areas of the United States, begun just prior to the turn of the 20th century.
Rust
A brown mold resembling the rust in iron. Rust affects stamp paper and gum in tropical regions.

Secret mark
A minute alteration to a stamp design added to distinguish later printings from earlier printings by a different firm. Secret marks may positively distinguish genuine stamps from counterfeits.
Seebeck
The nickname for various Latin American issues produced 1890-99 in contract with Nicholas Frederick Seebeck, the agent for the Hamilton Bank Note Co. of New York. Seebeck agreed to provide new issues of stamps and stationery each year at no charge, in return for the right to sell remainders and reprints to collectors. The resulting furor destroyed Seebeck and blackened the philatelic reputations of the countries involved.
Self-adhesive
Stamp gum that adheres to envelope paper by the application of pressure alone. Most self-adhesive stamps are sold on a coated paper release liner. See also Liner, Linerless, Water-activated.
Selvage
The marginal paper on a sheet or pane of stamps. Selvage may be unprinted or may contain printer's markings or other information.
Semi-postal

Series
A group of stamps with a similar design or theme, issued over a period of time. A series may be planned or may evolve.
Service inscribed
A stamp with wording as part of the initial printed design that identifies the mail-handling service for which the stamp is intended, such as "Presorted First-Class." See also Precancel.
Set
Stamps sharing common design elements, often issued at one time and usually collected as a group.
Shade

Sleeve
1) A seamless cylindrical printing plate used in rotary intaglio printing.
2) A flat transparent holder, often specifically for protecting and storing a cover.
Soaking
Removal of stamps from envelope paper. Most stamps may be safely soaked in water. Fugitive inks, however, will run in water, and chalky-surfaced papers will lose their designs entirely, so some knowledge of stamps is a necessity. Colored envelope paper should be soaked separately.
Souvenir card
A philatelic card, not valid for postage, issued in conjunction with some special event. The souvenir card often illustrates the design of a postage stamp.
Souvenir sheet
A small sheet of stamps, including one value or a set of stamps. A souvenir sheet usually has a wide margin and an inscription describing an event being commemorated. Stamps on a souvenir sheet may be perforated or imperforate.

They are printed in substantially greater quantities than commemorative stamps, and sometimes return to press for additional printings. Love stamps are also considered special stamps.
Specialist
A stamp collector who intensively studies and collects the stamps and postal history of a given country, area, or time period, or who has otherwise limited his collecting field.
Specimen
Stamp or stationery item distributed to Universal Postal Union members for identification purposes and to the philatelic press and trade for publicity purposes. Specimens are overprinted or punched with the word "SPECIMEN'' or its equivalent, or are overprinted or punched in a way to make them different from the issued stamps. Specimens of scarce stamps tend to be less valuable than the actual stamps. Specimens of relatively common stamps are more valuable.
Speculative issue
A stamp or issue released primarily for sale to collectors, rather than to meet any legitimate postal need.
Splice
The repair of a break in a roll of stamp paper, or the joining of two rolls of paper for continuous printing. Stamps printed over a splice are usually removed and destroyed before the normal stamps are issued.

T
Abbreviation for the French "Taxe.'' Handstamped on a stamp, the T indicates the stamp's use as a postage due. Handstamped on a cover, it indicates that postage due has been charged. Several countries have used regular stamps with a perforated initial T as postage dues.
Tagging
Phosphor material on stamps used to activate automatic mail-handling equipment. This may be lines, bars, letters, part of the design area or the entire stamp surface. The tagging may also permeate the stamp paper. Some stamps are issued both with and without tagging. Catalogues describe them as tagged or untagged.
Teeth
The protruding points along the outer edge of a perforated postage stamp when it has been removed from the pane.
Telegraph stamp
Label used for the prepayment of telegraph fees. Telegraph stamps resemble postage stamps.

Underprint
A fine printing underlying the design of a stamp, most often used to deter counterfeiting.
Ungummed
A stamp without gum. Ungummed stamps are either stamps issued without gum or an uncanceled gummed stamp that has had its gum soaked off. Many countries in tropical climates have issued stamps without gum.
Unhinged
A stamp without hinge marks, but not necessarily with original gum.
Unused
An uncanceled stamp that has not been used but has a hinge mark or some other characteristic or defect that keeps it from being considered a mint stamp. Uncanceled stamps without gum may have been used and missed being canceled, or they may have lost their gum by accident.
