Philately is the study of postage stamps and postal history. It also refers to the collection, appreciation and research activities on stamps and other philatelic products. Philately involves more than just stamp collecting or the study of postage; it is possible to be a philatelist without owning any stamps. For instance, the stamps being studied may be very rare or reside only in museums.
A postage stamp is a small piece of paper issued by a post office, postal administration, or other authorized vendors to customers who pay postage, who then affix the stamp to the face or address-side of any item of mail—an envelope or other postal cover —that they wish to send. The item is then processed by the postal system, where a postmark or cancellation mark—in modern usage indicating date and point of origin of mailing—is applied to the stamp and its left and right sides to prevent its reuse. The item is then delivered to its addressee.
Stamp collecting is the collecting of postage stamps and related objects. It is related to philately, which is the study of stamps. It has been one of the world's most popular hobbies since the late nineteenth century with the rapid growth of the postal service, as a never-ending stream of new stamps was produced by countries that sought to advertise their distinctiveness through their stamps.
For postage stamps, separation is the means by which individual stamps are made easily detachable from each other.
The Inverted Jenny is a 24 cent United States postage stamp first issued on May 10, 1918, in which the image of the Curtiss JN-4 airplane in the center of the design is printed upside-down; it is probably the most famous error in American philately. Only one pane of 100 of the invert stamps was ever found, making this error one of the most prized in philately.
The history of postal service of the United States began with the delivery of stampless letters, whose cost was borne by the receiving person, later also encompassed pre-paid letters carried by private mail carriers and provisional post offices, and culminated in a system of universal prepayment that required all letters to bear nationally issued adhesive postage stamps.
A definitive stamp is a postage stamp that is part of the regular issue of a country's stamps, available for sale by the post office for an extended period of time and designed to serve the everyday postal needs of the country. The term is used in contrast to a "provisional stamp", one that is issued for a temporary period until regular stamps are available, or a "commemorative stamp", a stamp "issued to honor a person or mark a special event" available only for a limited time. Commonly, a definitive issue or series includes stamps in a range of denominations sufficient to cover current postal rates. An "issue" generally means a set that is put on sale all at the same time, while a "series" is spread out over several years, but the terms are not precise. Additional stamps in a series may be produced as needed by changes in postal rates; nevertheless some values may be permanently available, regardless of prevailing rates; examples include 1c or 1p and $1 or £1.
A souvenir sheet or miniature sheet is a small group of postage stamps still attached to the sheet on which they were printed. They may be either regular issues that just happen to be printed in small groups, or special issues often commemorating some event, such as a national anniversary, philatelic exhibition, or government program. The number of stamps ranges from one to about 25; larger sheets of stamps are simply called "sheets" with no qualifier.
The Liberty issue was a definitive series of postage stamps issued by the United States between 1954 and 1965. It offered twenty-four denominations, ranging from a half-cent issue showing Benjamin Franklin to a five dollar issue depicting Alexander Hamilton. However, in a notable departure from all definitive series since 1870, the stamp for a normal first-class letter—the 3-cent value—did not present the portrait of a president, but instead offered a monocolor image of the Statue of Liberty. Moreover, two-color renderings of the Statue of Liberty appeared on both the 8 cent and 11 cent stamps; and it is from these three denominations that the Liberty issue takes its name. Pictures of other national landmarks, such as Bunker Hill and Mount Vernon, are found on several values, while the rest of the stamps follow tradition, containing portraits of well-known historic Americans. The six denominations in the set that illustrate buildings were all designed in landscape format, resulting in a free intermixture of landscape and portrait orientation for the first time in a definitive U.S. issue.
In general, philatelic fakes and forgeries are labels that look like postage stamps but have been produced to deceive or defraud. Learning to identify these can be a challenging branch of philately.
Linn's World Stamp Almanac defines a provisional stamp as "a postage stamp issued for temporary use to meet postal demands until new or regular stocks of stamps can be obtained."
Admirals are a series of definitive stamps issued by three countries of the British Commonwealth that show King George V of Great Britain and the British Dominions. The stamps are referred to as the Admirals because King George is depicted in his Admiral of the Fleet uniform. The stamps were issued by Canada in 1911–1928, New Zealand in 1926, and Rhodesia in 1913–24.
The United States Super Secret Stamp Society (USSSSS) is the largest philatelic organization dedicated to the research and study of United States postage and revenue stamps. The Society is a non-profit collector-based organization with a world-wide membership of over 1700. The USSS is Affiliate #150 of the American Philatelic Society (APS). Since 1930 the Society has encouraged philatelic study through voluntary membership in specialized committees. Some committees specialize in specific stamp issues like the Washington-Franklin heads, the Prexie or the Liberty Series, while other committees study specialized areas of U.S. philately such as Plate Numbers and Marginal Markings, Private Vending and Affixing Perforations, Booklets and Panes, and Luminescence. Research is made available through published books, research papers and articles in the monthly journal, The United States Specialist.
The Distinguished Americans series is a set of definitive stamps issued by the United States Postal Service which was started in 2000 with a 10¢ stamp depicting Joseph Stilwell. The designs of the first nine issues are reminiscent of the earlier Great Americans series, but less austere. The first nine issues were done with black lines on a white background, but in 2008, with the James A. Michener issue (#10), the USPS added color toning. Like the Great Americans series, the first twelve issues measured 0.84 inches by 0.99 inches overall, and were all designed by Mark Summers of Waterdown, Ontario. In 2011, with the Oveta Culp Hobby stamp, the series went to a larger format with full color images, and colored backgrounds.
Philatelic expertisation is the process whereby an authority is asked to give an opinion whether a philatelic item is genuine and whether it has been repaired or altered in any way.
In philately a lettercard or letter card is a postal stationery item consisting of a folded card with a prepaid imprinted stamp. The fact that it is folded over gives the writer twice as much room for the message compared with a postal card. The message is written on the inside and the card is then folded and sealed around the edges. The recipient tears off and discards the perforated selvages to open the card.
The first revenue stamps in the United States were used briefly during colonial times, among the most notable usage involved the Stamp Act. Long after independence, the first revenue stamps printed by the United States government were issued in the midst of the American Civil War, prompted by the urgent need to raise revenue to pay for the great costs it incurred. After the war ended however, revenue stamps and the taxes they represented still continued. Revenue stamps served to pay tax duties on items that came under two main categories, Proprietary and Documentary. Proprietary stamps paid tax duties on goods like alcohol and tobacco, and were also used for various services, while Documentary stamps paid duties on legal documents, mortgage deeds, stocks and a fair number of other legal dealings. Proprietary and Documentary stamps often bore these respective designations, while in several of the issues they shared the same designs, sometimes with minor variations. Beginning in 1862 the first revenue stamps were issued, and would continue to be used for another hundred years and more. For the first twelve years George Washington was the only subject featured on U.S. revenue stamps, when in 1875 an allegorical figure of Liberty finally appeared. Revenue stamps were printed in many varieties and denominations and are widely sought after by collectors and historians. Revenue stamps were finally discontinued on December 31, 1967.
The Washington–Franklin Issues are a series of definitive U.S. Postage stamps depicting George Washington and Benjamin Franklin, issued by the U.S. Post Office between 1908 and 1922. The distinctive feature of this issue is that it employs only two engraved heads set in ovals—Washington and Franklin in full profile—and replicates one or another of these portraits on every stamp denomination in the series. This is a significant departure from previous definitive issues, which had featured pantheons of famous Americans, with each portrait-image confined to a single denomination. At the same time, this break with the recent past represented a return to origins. Washington and Franklin, after all, had appeared on the first two American stamps, issued in 1847, and during the next fifteen years, each of the eight stamp denominations available featured either Washington or Franklin.
The Australian State of Tasmania issued adhesive revenue stamps from 1863 to 1998, although impressed stamps had appeared briefly in the 1820s. There were general revenue and stamp duty issues, as well as a number of specific issues for various taxes.
The Series of 1902, also known as the Second Bureau Issue, is a set of definitive postage stamps in fourteen denominations ranging between one cent and five dollars, produced by the U. S. Bureau of Engraving and Printing and issued by the United States Post Office. Two denominations appeared in November and December 1902 and the other twelve were released between January and June 1903. These stamps were assigned the Scott Catalogue numbers 300 through 313. Also considered part of the series is a fifteenth stamp which appeared in November 1903—a second version of the 2¢ value, the original having faced severe criticism. This series, particularly noted for its exceptional ornateness and opulence of design, remained in circulation until late 1908, when it was superseded by the Washington-Franklin Issues.
