Numismatics is the study or collection of currency, including coins, tokens, paper money, medals and related objects.

Specialists, known as numismatists, are often characterized as students or collectors of coins, but the discipline also includes the broader study of money and other means of payment used to resolve debts and exchange goods.

The earliest forms of money used by people are categorised by collectors as "odd and curious", but the use of other goods in barter exchange is excluded, even where used as a circulating currency (e.g., cigarettes or instant noodles in prison). As an example, the Kyrgyz people used horses as the principal currency unit, and gave small change in lambskins; the lambskins may be suitable for numismatic study, but the horses are not. Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems. (Full article...)

  The Louisiana Purchase Exposition gold dollar is a commemorative coin issue dated 1903. Struck in two varieties, the coins were designed by United States Bureau of the Mint Chief Engraver Charles E. Barber. The pieces were issued to commemorate the Louisiana Purchase Exposition held in 1904 in St. Louis; one variety depicted former president Thomas Jefferson, and the other, the recently assassinated president William McKinley. Although not the first American commemorative coins, they were the first in gold.
  
  Promoters of the Louisiana Purchase Exposition, originally scheduled to open in 1903, sought a commemorative coin for fundraising purposes. Congress authorized an issue in 1902, and exposition authorities, including numismatic promoter Farran Zerbe, sought to have the coin issued with two designs, to aid sales. The price for each variety was $3, the same cost whether sold as a coin, or mounted in jewelry or on a spoon. (Full article...)

  The Gadsden Purchase half dollar was a proposed commemorative coin to be issued by the United States Bureau of the Mint. Legislation for the half dollar passed both houses of Congress in 1930 but was vetoed by President Herbert Hoover. The House of Representatives sustained his action, 96 votes in favor of overriding it to 243 opposed, well short of the necessary two-thirds majority. This was the first veto of Hoover's presidency and the first ever for a commemorative coin bill.
  
  The proposal to commemorate the 1854 congressional ratification of the Gadsden Purchase was the brainchild of El Paso coin dealer Lyman W. Hoffecker, who wanted a commemorative coin he could control and distribute. He gained the support of several members of Congress from Texas and the Southwest, and a bill was introduced in Congress in April 1929, receiving a hearing 11 months later. Treasury Secretary Andrew W. Mellon sent a letter and two officials in opposition to the bill, but it passed both houses of Congress without dissent. On April 21, 1930, Hoover vetoed the bill, deeming commemorative coins abusive. Although only one congressman spoke in favor of Hoover's action during the override debate in the House, the veto was easily sustained. (Full article...)

  The Bridgeport, Connecticut, Centennial half dollar (also the Bridgeport Centennial half dollar or Bridgeport half dollar) is a commemorative fifty-cent piece issued in 1936 by the United States Bureau of the Mint to honor the 100th anniversary of the incorporation of Bridgeport, Connecticut, as a city. Designed by Henry Kreis, the obverse depicts the showman P. T. Barnum, who was one of Bridgeport's most famous residents, was mayor of the city, helped develop it, and is buried there. The reverse depicts a stylized eagle.
  
  Bridgeport authorities wanted a commemorative coin to help fund the centennial celebrations. At the time, Congress was authorizing such coins for even local events, and the Bridgeport half dollar legislation passed Congress without opposition. Kreis had designed the Connecticut Tercentenary half dollar (1935), and he produced designs showing a left-facing Barnum and a modernistic eagle similar to the one on the Connecticut piece.

  The Columbian half dollar is a coin issued by the Bureau of the Mint in 1892 and 1893. The first traditional United States commemorative coin, it was issued both to raise funds for the 1893 World's Columbian Exposition and to mark the quadricentennial of the first voyage to the Americas of Christopher Columbus, whose portrait it bears. The Columbian half dollar was the first American coin to depict a historical person.
  
  The coin stems from the desire of the Columbian Exposition's organizers to gain federal money to complete construction of the fair. Congress granted an appropriation, and allowed it to be in the form of commemorative half dollars, which legislators and organizers believed could be sold at a premium. Fair official James Ellsworth wanted the new coin to be based on a 16th-century painting he owned by Lorenzo Lotto, reputedly of Columbus, and pushed for this through the design process. When initial sketches by Mint Chief Engraver Charles E. Barber proved unsatisfactory, fair organizers turned to a design by artist Olin Levi Warner, which after modification by Barber and his assistant, George T. Morgan, was struck by the Mint.

  The Saint-Gaudens double eagle is a twenty-dollar gold coin, or double eagle, produced by the United States Mint from 1907 to 1933. The coin is named after its designer, the sculptor Augustus Saint-Gaudens, who designed the obverse and reverse. It is considered by many to be the most beautiful of U.S. coins.
  
  In 1904, President Theodore Roosevelt sought to beautify American coinage, and proposed Saint-Gaudens as an artist capable of the task. Although the sculptor had poor experiences with the Mint and its chief engraver, Charles E. Barber, Saint-Gaudens accepted Roosevelt's call. The work was subject to considerable delays, due to Saint-Gaudens's declining health and difficulties because of the high relief of his design. Saint-Gaudens died in 1907, after designing the eagle and double eagle, but before the designs were finalized for production. (Full article...)

  The British farthing (derived from the Old English feorthing, a fourth part) was a British coin worth a quarter of an old penny (1⁄960 of a pound sterling). It ceased to be struck after 1956 and was demonetised from 1 January 1961.
  
  The British farthing is a continuation of the English farthing, struck by English monarchs prior to the Act of Union 1707 which unified the crowns of England and Scotland into the Kingdom of Great Britain. Only pattern farthings were struck under Queen Anne as there was a glut of farthings from previous reigns. The coin was struck intermittently under George I and George II, but by the reign of George III, counterfeits were so prevalent the Royal Mint ceased striking copper coinage after 1775. The next farthings were the first struck by steam power, in 1799 by Matthew Boulton at his Soho Mint under licence. Boulton coined more in 1806, and the Royal Mint resumed production in 1821. The farthing was struck fairly regularly under George IV and William IV. By then it carried a scaled-down version of the penny's design, and would continue to mirror the penny and halfpenny until after 1936. (Full article...)

  The Lynchburg Sesquicentennial half dollar was a commemorative half dollar designed by Charles Keck and struck by the United States Bureau of the Mint in 1936, to celebrate the 150th anniversary of the 1786 incorporation of the independent city of Lynchburg, Virginia. The obverse of the coin depicts former Secretary of the Treasury and U.S. Senator Carter Glass, a native of Lynchburg. The reverse depicts a statue of the Goddess of Liberty, with Lynchburg sites behind her, including the Old Courthouse and the city's Confederate monument.
  
  Glass sponsored legislation for the half dollar, which passed Congress without difficulty. The Commission of Fine Arts proposed that the coin should bear the portrait of John Lynch, founder of Lynchburg, on the obverse, but no portrait of him was known. Instead, the Lynchburg Sesqui-Centennial Association decided Senator Glass should be on the coin. Despite his opposition, Glass became the third living person to appear on a U.S. coin, and the first to be shown alone. (Full article...)

  The gold dollar or gold one-dollar piece is a gold coin that was struck as a regular issue by the United States Bureau of the Mint from 1849 to 1889. The coin had three types over its lifetime, all designed by Mint Chief Engraver James B. Longacre. The Type 1 issue has the smallest diameter (0.5 inch =12.7mm) of any United States coin minted to date.
  
  A gold dollar coin had been proposed several times in the 1830s and 1840s, but was not initially adopted. Congress was finally galvanized into action by the increased supply of bullion caused by the California gold rush, and in 1849 authorized a gold dollar. In its early years, silver coins were being hoarded or exported, and the gold dollar found a ready place in commerce. Silver again circulated after Congress in 1853 required that new coins of that metal be made lighter, and the gold dollar became a rarity in commerce even before federal coins vanished from circulation because of the economic disruption caused by the American Civil War.

  The Lexington–Concord Sesquicentennial half dollar, sometimes the Lexington–Concord half dollar or Patriot half dollar, is a commemorative fifty-cent piece struck by the United States Bureau of the Mint in 1925 in honor of the 150th anniversary of the Battles of Lexington and Concord, which began the American Revolutionary War. It was designed by Chester Beach and features Daniel Chester French's 1874 The Minute Man statue on the obverse.
  
  Members of the Massachusetts congressional delegation introduced legislation in 1924 which would provide for a commemorative half dollar for the anniversary. The bill passed both houses of Congress and was signed by President Calvin Coolidge. Beach had to satisfy committees from both Lexington and Concord, and the Commission of Fine Arts passed the design only reluctantly, feeling Beach had been given poor materials to work with.

  The Kennedy half dollar, first minted in 1964, is a fifty-cent coin issued by the United States Mint. Intended as a memorial to the assassinated 35th president of the United States John F. Kennedy, it was authorized by Congress just over a month after his death. Use of existing works by Mint sculptors Gilroy Roberts and Frank Gasparro allowed dies to be prepared quickly, and striking of the new coins began in January 1964.
  
  The silver coins were hoarded upon their release in March 1964 by collectors and those interested in a memento of the late president. Although the Mint greatly increased production, the denomination was seldom seen in circulation. Continued rises in the price of silver increased the hoarding—many early Kennedy half dollars have been melted for their silver content. Starting with 1965-dated coins, the percentage of fine silver was reduced from 90% to 40% (silver clad), but even with this change the coin saw little circulation. (Full article...)

  The Shield nickel was the first United States five-cent piece to be made out of copper-nickel, the same alloy of which American nickels are struck today. Designed by James B. Longacre, the coin was issued from 1866 until 1883, when it was replaced by the Liberty Head nickel. The coin takes its name from the motif on its obverse, and was the first five-cent coin referred to as a "nickel"—silver pieces of that denomination had been known as half dimes.
  
  Silver half dimes had been struck from the early days of the United States Mint in the late 18th century. Those disappeared from circulation, along with most other coins, in the economic turmoil of the Civil War. In 1864, the Mint successfully introduced low-denomination coins, whose intrinsic worth did not approach their face value. Industrialist Joseph Wharton advocated coins containing nickel—a metal in which he had significant financial interests. When the Mint proposed a copper-nickel five-cent piece, Congress required that the coin be heavier than the Mint had suggested, allowing Wharton to sell more of the metal to the government.

  The Liberty Head double eagle or Coronet double eagle is an American twenty-dollar gold piece struck as a pattern coin in 1849, and for commerce from 1850 to 1907. It was designed by Mint of the United States Chief Engraver James B. Longacre.
  
  The largest denomination of United States coin authorized by the Mint Act of 1792 was the eagle, or ten-dollar piece. The large amount of bullion being brought east after the discovery of gold in California in the 1840s caused Congress to consider new denominations of gold coinage. The gold dollar and double eagle were the result. After considerable infighting at the Philadelphia Mint, Chief Engraver James B. Longacre designed the double eagle, and it began to be issued for commerce in 1850. Only one 1849 double eagle is known to survive and it rests in the National Numismatic Collection at the Smithsonian. (Full article...)

  The penny of Great Britain and the United Kingdom from 1714 to 1901, the period in which the House of Hanover reigned, saw the transformation of the penny from a little-used small silver coin to the bronze piece recognisable to modern-day Britons. All bear the portrait of the monarch on the obverse; copper and bronze pennies have a depiction of Britannia, the female personification of Britain, on the reverse.
  
  During most of the 18th century, the penny was a small silver coin rarely seen in circulation, and that was principally struck to be used for Maundy money or other royal charity. Beginning in 1787, the chronic shortage of good money resulted in the wide circulation of private tokens, including large coppers valued at one penny. In 1797 industrialist Matthew Boulton gained a contract to produce official pennies at his Soho Mint in Birmingham; he struck millions of pennies over the next decade. After that, it was not until 1825 that pennies were struck again for circulation, and the copper penny continued to be issued until 1860. (Full article...)

  The Waterloo Medal was designed by Italian-born sculptor Benedetto Pistrucci. He worked on it from 1819 to 1849, when the completed matrices were presented to Britain's Royal Mint. The medal was commissioned by the British Government in 1819 on the instructions of the Prince Regent (later George IV); copies were to be presented to the generals who had been victorious in the 1815 Battle of Waterloo, and to the leaders of Britain's allies. As most of the intended recipients had died by 1849, and relations with France had improved, the medals were never struck, though modern-day editions have been made for sale to collectors.
  
  In 1816, the Prince Regent had first suggested a medal to be presented to allies and commanders from Waterloo. The Royal Academy proposed work by John Flaxman, one of its members, but Pistrucci, whose responsibility it was to engrave the dies, refused to copy another's work, and brought forth designs of his own. The Prince Regent and William Wellesley-Pole, Master of the Mint were impressed by Pistrucci's models, and he gained the commission. (Full article...)

  The Elgin, Illinois, Centennial half dollar was a fifty-cent commemorative coin issued by the United States Bureau of the Mint in 1936, part of the wave of commemoratives authorized by Congress and struck that year. Intended to commemorate the centennial of the founding of Elgin, the piece was designed by local sculptor Trygve Rovelstad. The obverse depicts an idealized head of a pioneer man. The reverse shows a grouping of pioneers, and is based upon a sculptural group that Rovelstad hoped to build as a memorial to those who settled Illinois, but which was not erected in his lifetime.
  
  Rovelstad had heard of other efforts to gain authorization for commemorative coins, which were sold by the Mint to a designated group at face value and then retailed to the public at a premium. In 1935, through his congressman, he had legislation introduced into the House of Representatives for a commemorative coin in honor of Elgin's centennial that year. Rovelstad hoped that the proposed coin would both depict and be a source of funds for his memorial to the pioneers. Texas coin dealer L.W. Hoffecker heard of the effort and contacted Rovelstad to offer his assistance—Hoffecker had been a force behind the Old Spanish Trail half dollar, issued in 1935 and distributed by him.

Banknotes of the Australian dollar in a wallet. In 1988, Australia was the first country to introduce polymer banknotes for circulation.

Polymer banknotes are banknotes made from a synthetic polymer such as biaxially oriented polypropylene (BOPP). Such notes incorporate many security features not available in paper banknotes, including the use of metameric inks. Polymer banknotes last significantly longer than paper notes, causing a decrease in environmental impact and a reduced cost of production and replacement. Modern polymer banknotes were first developed by the Reserve Bank of Australia (RBA), Commonwealth Scientific and Industrial Research Organisation (CSIRO) and The University of Melbourne. They were first issued as currency in Australia during 1988 (coinciding with Australia's bicentennial year); by 1996, the Australian dollar was switched completely to polymer banknotes. Romania was the first country in Europe to issue a plastic note in 1999 and became the third country after Australia and New Zealand to fully convert to polymer by 2003.

Other currencies that have been switched completely to polymer banknotes include: the Vietnamese đồng (2006) although this is only applied to banknotes with denominations above 5,000 đồng, the Brunei dollar (2006), the Nigerian Naira (2007), the Papua New Guinean kina (2008), the Canadian dollar (2013), the Maldivian rufiyaa (2017), the Mauritanian ouguiya (2017), the Nicaraguan córdoba (2017), the Vanuatu vatu (2017), the Eastern Caribbean dollar (2019), the pound sterling (2021) and the Barbadian dollar (2022). Several countries and regions have now introduced polymer banknotes into commemorative or general circulation, including: Nigeria, Cape Verde, Chile, The Gambia, Trinidad and Tobago, Vietnam, Mexico, Singapore, Malaysia, Botswana, São Tomé and Príncipe, North Macedonia, Russia, Solomon Islands, Samoa, Morocco, Albania, Sri Lanka, Hong Kong, Israel, China, Taiwan, Kuwait, Mozambique, Saudi Arabia, Isle of Man, Guatemala, Haiti, Jamaica, Libya, Mauritius, Costa Rica, Honduras, Angola, Namibia, Lebanon, the Philippines, and Egypt.

The Mercury dime is a ten-cent coin struck by the United States Mint from late 1916 to 1945. Designed by Adolph Weinman and also referred to as the Winged Liberty Head dime, it gained its common name because the obverse depiction of a young Liberty, identifiable by her winged Phrygian cap, was confused with the Roman god Mercury. Weinman is believed to have used Elsie Stevens, the wife of lawyer and poet Wallace Stevens, as a model. The coin's reverse depicts a fasces, symbolizing unity and strength, and an olive branch, signifying peace.

By 1916, the dime, quarter, and half dollar designed by Mint Chief Engraver Charles E. Barber had been struck for 25 years, and could be replaced by the Treasury, of which the Mint is a part, without Congressional authorization. Mint officials were under the misapprehension that the designs had to be changed, and held a competition among three sculptors, in which Barber, who had been in his position for 36 years, also took part. Weinman's designs for the dime and half dollar were selected. (Full article...)
