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 (the cost involved in moving, insuring, or registering mail). Then the stamp is affixed to the face or address-side of any item of mail—an envelope or other postal cover (e.g., packet, box, mailing cylinder)—which 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. Next the item is delivered to its address.

Always featuring the name of the issuing nation (with the exception of the United Kingdom), a denomination of its value, and often an illustration of persons, events, institutions, or natural realities that symbolize the nation's traditions and values, every stamp is printed on a piece of usually rectangular, but sometimes triangular or otherwise shaped special custom-made paper whose back is either glazed with an adhesive gum or self-adhesive.

Because governments issue stamps of different denominations in unequal numbers and routinely discontinue some lines and introduce others, and because of their illustrations and association with the social and political realities of the time of their issue, they are often prized for their beauty and historical significance by stamp collectors, whose study of their history and of mailing systems is called philately. Because collectors often buy stamps from an issuing agency with no intention to use them for postage, the revenues from such purchases and payments of postage can make them a source of net profit to that agency. On 1 May 1840, Sir Rowland Hill invented the Penny Black, the first adhesive postage stamp issued in the United Kingdom, selecting a simple design that showed Queen Victoria's profile. The artist Henry Corbould drew her image, basing his work on a medal by William Wyon. Perkins, Bacon & Petch, a leading security printing firm printed the stamp. Within three years postage stamps were introduced in Switzerland and Brazil, a little later in the United States, and by 1860, they were in 90 countries around the world. The first postage stamps did not need to show the issuing country, so no country name was included on them. Thus the United Kingdom remains the only country in the world to omit its name on postage stamps; the monarch's image signifies the United Kingdom as the country of origin. The LPP was a mail system that delivered letters and small parcels up to a pound in weight and £10 in value inside the city of London for the sum of one penny.

In 1835, the civil servant Lovrenc Košir from Ljubljana in Austria-Hungary (now Slovenia), suggested the use of "artificially affixed postal tax stamps" using "gepresste Papieroblate" ("pressed paper wafers"), but although civil bureaucrats considered the suggestion in detail, it was not adopted. The 'Papieroblate' were to produce stamps as paper decals so thin as to prevent their reuse.

Rowland Hill

thumb|upright|Rowland Hill

In 1836, Robert Wallace, a Member of (British) Parliament, gave Sir Rowland Hill numerous books and documents about the postal service, which Hill described as a "half hundred weight of material". After a detailed study, on 4 January 1837 Hill submitted a pamphlet entitled Post Office Reform: Its Importance and Practicability to the Chancellor of the Exchequer, Thomas Spring Rice, which was marked "private and confidential", and not released to the general public. The Chancellor summoned Hill to a meeting at which he suggested improvements and changes to be presented in a supplement, which Hill duly produced and submitted on 28 January 1837. Hill wrote Post Office Reform while he served as secretary of the South Australian Colonization Commission. The colonization of South Australia roughly followed Edward Gibbon Wakefield's scheme of colonization which emphasized the uniform pricing of land, and Wakefield's ideas influenced Hill's argument for the uniform pricing of postal rates.

Summoned to give evidence before the Commission for Post Office Enquiry on 13 February 1837, Hill read from the letter he wrote to the Chancellor that included a statement saying that the notation of paid postage could be created... "by using a bit of paper just large enough to bear the stamp, and covered at the back with a glutinous wash..." This would eventually become the first unambiguous description of a modern adhesive postage stamp (though the term "postage stamp" originated at a later date). Shortly afterward, Hill's revision of the booklet, dated 22 February 1837, containing some 28,000 words, incorporating the supplement given to the Chancellor and statements he made to the commission, was published and made available to the general public. Hansard records that on 15 December 1837, Benjamin Hawes asked the Chancellor of the Exchequer "whether it was the intention of the Government to give effect to the recommendation of the Commissioners of the Post-office, contained in their ninth report relating to the reduction of the rates of postage, and the issuing of penny stamps?"

Hill's ideas for postage stamps and charging paid-postage based on weight soon took hold, and were adopted in many countries throughout the world.

Rowland Hill and the reforms he introduced to the United Kingdom postal system appear on several of its commemorative stamps.

The first independent evidence for Chalmers' claim is an essay, dated 8 February 1838 and received by the Post Office on 17 February 1838, in which he proposed adhesive postage stamps to the General Post Office. In this approximately 800-word document concerning methods of indicating that postage had been paid on mail he states:

Chalmers' original document is now in the United Kingdom's National Postal Museum.

Since Chalmers used the same postage denominations that Hill had proposed in February 1837, it is clear that he was aware of Hill's proposals, but whether he obtained a copy of Hill's booklet or simply read about it in one or both of the two detailed accounts (25 March 1837 and 20 December 1837) published in The Times is unknown. Neither article mentioned "a bit of paper just large enough to bear the stamp", so Chalmers could not have known that Hill had made such a proposal. This suggests that either Chalmers had previously read Hill's booklet and was merely elaborating Hill's idea, or he had independently developed the idea of the modern postage stamp.

James Chalmers organized petitions "for a low and uniform rate of postage". The first such petition was presented in the House of Commons on 4 December 1837 (from Montrose). Further petitions which he organized were presented on 1 May 1838 (from Dunbar and Cupar), 14 May 1838 (from the county of Forfar), and 12 June 1839. At this same time, other groups organized petitions and presented them to Parliament. All petitions for consumer-oriented, low-cost, volume-based postal rates followed publication of Hill's proposals.

History

The nineteenth century

thumb|The [[Penny Black, the world's first postage stamp (1 May 1840)]]

Postage stamps have facilitated the delivery of mail since the 1840s. Before then, ink and hand-stamps (hence the word 'stamp'), usually made from wood or cork, were often used to frank the mail and confirm the payment of postage. The first adhesive postage stamp, commonly referred to as the Penny Black, was issued in the United Kingdom in 1840. The invention of the stamp was part of an attempt to improve the postal system in the United Kingdom of Great Britain and Ireland, which, in the early 19th century, was in disarray and rife with corruption. There are varying accounts of the inventor or inventors of the stamp.

Before the introduction of postage stamps, mail in the United Kingdom was paid for by the recipient, a system that was associated with an irresolvable problem: the costs of delivering mail were not recoverable by the postal service when recipients were unable or unwilling to pay for delivered items, and senders had no incentive to restrict the number, size, or weight of items sent, whether or not they would ultimately be paid for. The postage stamp resolved this issue in a simple and elegant manner, with the additional benefit of room for an element of beauty to be introduced. Concurrently with the first stamps, the United Kingdom offered wrappers for mail. Later related inventions include postal stationery such as prepaid-postage envelopes, post cards, lettercards, aerogrammes, and postage meters.

The postage stamp afforded convenience for both the mailer and postal officials, more effectively recovered costs for the postal service, and ultimately resulted in a better, faster postal system. With the conveniences stamps offered, their use resulted in greatly increased mailings during the 19th and 20th centuries.

As postage stamps with their engraved imagery began to appear on a widespread basis, historians and collectors began to take notice. The study of postage stamps and their use is referred to as philately. Stamp collecting can be both a hobby and a form of historical study and reference, as government-issued postage stamps and their mailing systems have always been involved with the history of nations.

Although a number of people laid claim to the concept of the postage stamp, it is well documented that stamps were first introduced in the United Kingdom of Great Britain and Ireland on 1 May 1840 as a part of postal reforms promoted by Sir Rowland Hill.

The first stamp, the "Penny Black", became available for purchase 1 May 1840, to be valid as of 6 May 1840. Two days later, 8 May 1840, the Two Penny Blue was introduced. The Penny Black was sufficient for a letter less than half an ounce to be sent anywhere within the United Kingdom. Both stamps included an engraving of the young Queen Victoria, without perforations, as the first stamps were separated from their sheets by cutting them with scissors.

The first stamps did not need to show the issuing country, so no country name was included on them. The United Kingdom remains the only country to omit its name on postage stamps, using the reigning monarch's head as country identification. Following the introduction of the postage stamp in the United Kingdom, prepaid postage considerably increased the number of letters mailed. Before 1839, the number of letters sent in the United Kingdom was typically 76 million. By 1850, this increased five-fold to 350 million, continuing to grow rapidly until the end of the 20th century when newer methods of indicating the payment of postage reduced the use of stamps.

Other countries soon followed the United Kingdom with their own stamps. A few other countries issued stamps in the late 1840s. The famous Mauritius "Post Office" stamps were issued by Mauritius in September 1847. Many others, such as India, started their use in the 1850s, and by the 1860s most countries issued stamps.

Perforation of postage stamps began in January 1854. The first officially perforated stamps were issued in February 1854. Stamps from Henry Archer's perforation trials were issued in the last few months of 1850; during the 1851 parliamentary session

The twentieth and twenty-first centuries

After World War II, it became customary in some countries, especially small Arab nations, to issue postage stamps en masse as it was realized how profitable that was.

In December 2020, 590,000 people sent cards with these handwritten codes.

Design

When the first postage stamps were issued in the 1840s, they followed an almost identical standard in shape, size and general subject matter. They were rectangular in shape. They bore the images of queens, presidents and other political figures. They also depicted the denomination of the postage-paid, and with the exception of the United Kingdom, depicted the name of the country from which issued. Nearly all early postage stamps depict images of national leaders only.

Soon after the introduction of the postage stamp, other subjects and designs began to appear. Some designs were welcome, others widely criticized. For example, in 1869, the United States Post Office broke the tradition of depicting presidents or other famous historical figures, instead using other subjects including a train and horse.(See: 1869 Pictorial Issue.) The change was greeted with general disapproval, and sometimes harsh criticism from the American public.

Perforations

Perforations are small holes made between individual postage stamps on a sheet of stamps, facilitating separation of a desired number of stamps. The resulting frame-like, rippled edge surrounding the separated stamp defines a characteristic meme for the appearance of a postage stamp.

In the first decade of postage stamps' existence (depending on the country), stamps were issued without perforations. Scissors or other cutting mechanisms were required to separate a desired number of stamps from a full sheet. If cutting tools were not used, individual stamps were torn off. This is evidenced by the ragged edges of surviving examples. Mechanically separating stamps from a sheet proved an inconvenience for postal clerks and businesses, both dealing with large numbers of individual stamps on a daily basis. By 1850, methods such as rouletting wheels were being devised in efforts of making stamp separation more convenient, and less time-consuming.

The United Kingdom was the first country to issue postage stamps with perforations. The first machine specifically designed to perforate sheets of postage stamps was invented in London by Henry Archer, an Irish landowner and railroad man from Dublin, Ireland. The 1850 Penny Red was the first stamp to be perforated during trial course of Archer's perforating machine. After a period of trial and error and modifications of Archer's invention, new machines based on the principles pioneered by Archer were purchased and in 1854 the United Kingdom postal authorities started continuously issuing perforated postage stamps in the Penny Red and all subsequent designs.

In the United States, the use of postage stamps caught on quickly and became more widespread when on 3 March 1851, the last day of its legislative session, Congress passed the Act of March 3, 1851 (An Act to reduce and modify the Rates of Postage in the United States). Similarly introduced on the last day of the Congressional session four years later, the Act of March 3, 1855 required the prepayment of postage on all mailings. Thereafter, postage stamp use in the United States quickly doubled, and by 1861 had quadrupled. The original machine cut slits into the paper rather than punching holes, but the machine was soon modified.

Shapes and materials

In addition to the most common rectangular shape, stamps have been issued in geometric (circular, triangular and pentagonal) and irregular shapes. The United States issued its first circular stamp in 2000 as a hologram of the Earth. Sierra Leone and Tonga have issued stamps in the shapes of fruit. Stamps that are printed on sheets are generally separated by perforations, though, more recently, with the advent of gummed stamps that do not have to be moistened prior to affixing them, designs can incorporate smooth edges (although a purely decorative perforated edge is often present).

Stamps are most commonly made from paper designed specifically for them, and are printed in sheets, rolls, or small booklets. Less commonly, postage stamps are made of materials other than paper, such as embossed foil (sometimes of gold). Switzerland made a stamp that contained a bit of lace and one of wood. The United States produced one of plastic. East Germany issued a stamp of synthetic chemicals. In the Netherlands a stamp was made of silver foil. Bhutan issued one with its national anthem on a playable record.

Graphic characteristics

The subjects found on the face of postage stamps are generally what defines a particular stamp issue to the public and are often a reason why they are saved by collectors or history enthusiasts. Graphical subjects found on postage stamps have ranged from the early portrayals of kings, queens and presidents to later depictions of ships, birds and satellites, historical events, comics, dinosaurs, hobbies (knitting, stamp collecting), sports, holiday themes, and a plethora of other subjects too numerous to list.

Artists, designers, engravers and administrative officials are involved with the choice of subject matter and the method of printing stamps. Early stamp images were almost always produced from an engraving—a design etched into a steel die, which was then hardened and whose impression was transferred to a printing plate. Using an engraved image was deemed a more secure way of printing stamps as it was nearly impossible to counterfeit a finely detailed image with raised lines for anyone but a master engraver. In the mid-20th century, stamp issues produced by other forms of printing began to emerge, such as lithography, photogravure, intaglio and web offset printing. These later printing methods were less expensive and typically produced images of lesser quality.

Scents

Occasionally, postal authorities issue novelty "scented" or "aromatic" stamps which contain a scent, more readily apparent when rubbed. The effect is achieved by using ink which contains microcapsules that provide the desired fragrance when broken. chocolate, vanilla, cinnamon, pine needles or freshly baked bread. The first scented stamps were issued by Bhutan in 1973. Scott has a separate category and listing for United States Airmail Postage. Prior to 1940, the Scott Catalogue did not have a special designation for airmail stamps. The various major stamp catalogs have different numbering systems and may not always list airmail stamps the same way.

  • ATM stamp – stamps dispensed by automates and have their value imprinted only at the time of purchase
  • Booklet stamp – stamps produced and issued in booklet format
  • Carrier's stamp
  • Certified mail stamp
  • Cinderella stamp (see also: Poster stamp)
  • Coil stamps – tear-off stamps issued individually in a vending machine, or purchased in a roll
  • Commemorative stamp – a stamp which is issued for a limited time to commemorate a person or event Anniversaries of birthdays and historical events are among the most common examples.
  • Computer vended postage – advanced secure postage that uses information-based indicia (IBI) technology. IBI uses a two-dimensional bar code (Datamatrix or PDF417) to encode the originating address, date of mailing, postage and a digital signature to verify the stamp.
  • Customised stamp – a stamp on which the image can be chosen by the purchaser by sending in a photograph or by use of the computer. Some are not true stamps but technically meter labels.
  • Definitive stamps – stamps for everyday postage and are usually produced to meet current postal rates. They often have less appealing designs than commemoratives, though there are notable exceptions. The same design may be used for many years. The use of the same design over an extended period may lead to unintended colour varieties. This may make them just as interesting to philatelists as are commemoratives. A good example would be the US 1903 regular issues, their designs being very picturesque and ornamental. Starting in the mid-20th century some countries began assigning the first day of issue to a place associated with the subject of the stamp design, such as a specific town or city. There are two basic types of First Day Covers (FDCs) noted by collectors. The first and often most desirable type among advanced collectors is a cover sent through the mail in the course of everyday usage, without the intention of the envelope and stamp ever being retrieved and collected. The second type of FDC is often referred to as "Philatelic", that is, an envelope and stamp sent by someone with the intention of retrieving and collecting the mailed item at a later time and place. The envelope used for this type of FDC often bears a printed design or cachet of its own in correspondence with the stamp's subject and is usually printed well in advance of the first day of issue date. The latter type of FDC is usually far more common; it is usually inexpensive and relatively easy to acquire. Covers which were sent without any secondary purpose are considered non-philatelic and often are much more challenging to find and collect. All of these stamps are often found "canceled to order", meaning they are postmarked without ever having passed through the postal system. Most national post offices produce stamps that would not be produced if there were no collectors, some to a far more prolific degree than others.

Sales of stamps to collectors who do not use them for mailing can result in large profits. Examples of excessive issues have been the stamps produced by Nicholas F. Seebeck and stamps produced for the component states of the United Arab Emirates. Seebeck operated in the 1890s as an agent of Hamilton Bank Note Company. He approached Latin American countries with an offer to produce their entire postage stamp needs for free. In return. he would have exclusive rights to market stamps to collectors. Each year a new issue would be produced, but would expire at the end of the year. This assured Seebeck of a continuing supply of remainders.
