Electrum coin from Ephesus, 520-500 BCE. Obverse: Forepart of stag. Reverse: Square incuse punch

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 Roosevelt dime is the current dime, or ten-cent piece, of the United States. Struck by the United States Mint continuously since 1946, it displays President Franklin D. Roosevelt on the obverse and was authorized soon after his death in 1945.
  
  Roosevelt had been stricken with polio, and was one of the moving forces of the March of Dimes. The ten-cent coin could be changed by the Mint without the need for congressional action, and officials moved quickly to replace the Mercury dime. Chief Engraver John R. Sinnock prepared models, but faced repeated criticism from the Commission of Fine Arts. He modified his design in response, and the coin went into circulation in January 1946. (Full article...)

  The three-cent silver, also known as the three-cent piece in silver or trime, was struck by the Mint of the United States for circulation from 1851 to 1872, and as a proof coin in 1873. Designed by the Mint's chief engraver, James B. Longacre, it circulated well while other silver coinage was being hoarded and melted, but once that problem was addressed, became less used. It was abolished by Congress with the Coinage Act of 1873.
  
  After a massive importation of gold bullion during the California Gold Rush, silver could be traded for increasing amounts of gold, so U.S. silver coins were exported and melted for their metal. This, and the reduction of postage rates to three cents, prompted Congress in 1851 to authorize a coin of that denomination made of .750 fine silver, rather than the conventional .900. The three-cent silver was the first American coin to contain metal valued significantly less than its face value, and the first silver coin not to be legal tender for an unlimited amount. The coin saw heavy use until Congress acted again in 1853, making other silver coins lighter, which kept them in circulation. Congress also lightened the three-cent silver, and increased its fineness to 900 silver. (Full article...)

  The Lincoln cent (sometimes called the Lincoln penny) is a one-cent coin that has been struck by the United States Mint since 1909. The obverse or heads side was designed by Victor David Brenner, as was the original reverse, depicting two stalks of wheat (thus "wheat pennies", struck 1909–1958). The coin has seen several reverse, or tails, designs and now bears one by Lyndall Bass depicting a Union shield. All coins struck by the United States government with a value of 1⁄100 of a dollar are called cents because the United States has always minted coins using decimals. The penny nickname is a carryover from the coins struck in England, which went to decimals for coins in 1971.
  
  In 1905, sculptor Augustus Saint-Gaudens was hired by the Mint to redesign the cent and the four gold coins, which did not require congressional approval. Two of Saint-Gaudens's proposed designs for the cent were eventually adapted for the gold pieces, but Saint-Gaudens died in August 1907 before submitting additional designs for the cent. In January 1909, the Mint engaged Brenner to design a cent depicting the late president Abraham Lincoln, 1909 being the centennial year of his birth. It was the first widely circulating design of a U.S. president on a coin, an idea that had been seen as too monarchical in the past, namely by George Washington. Nevertheless, Brenner's design was eventually approved, and the new coins were issued to great public interest on August 2, 1909. (Full article...)

  The Old Spanish Trail half dollar is a commemorative coin struck by the United States Bureau of the Mint in 1935. The coin was designed by L. W. Hoffecker, a coin dealer, who also was in charge of its distribution.
  
  In 1930, President Herbert Hoover vetoed the Gadsden Purchase half dollar bill. Hoffecker had been the moving force behind that effort, and he sought another commemorative coin proposal that he could control if authorizing legislation was passed. He chose the travels of Spanish officer Álvar Núñez Cabeza de Vaca in the early 16th century. Hoffecker took liberties both with the timing of Cabeza de Vaca's travels and their location. For instance, although Hoffecker's hometown of El Paso, Texas, is featured on the coin, Cabeza de Vaca came nowhere near it. All this made little difference to Congress, which passed the Old Spanish Trail coin bill without opposition. It was signed into law by President Franklin D. Roosevelt. (Full article...)

  The Draped Bust dollar is a United States dollar coin minted from 1795 to 1803, and was reproduced, dated 1804, into the 1850s. The design succeeded the Flowing Hair dollar, which began mintage in 1794 and was the first silver dollar struck by the United States Mint. The designer is unknown, though the distinction is usually credited to artist Gilbert Stuart. The model is also unknown, though Ann Willing Bingham has been suggested.
  
  In October 1795, newly appointed Mint Director Elias Boudinot ordered that the legal fineness of 0.892 (89.2%) silver be used for the dollar rather than the unauthorized fineness of 0.900 (90%) silver that had been used since the denomination was first minted in 1794. Due largely to a decrease in the amount of silver deposited at the Philadelphia Mint, coinage of silver dollars declined throughout the latter years of the 18th century. In 1804, coinage of silver dollars was halted; the last date used during regular mint production was 1803. (Full article...)

  The Sacagawea dollar (also known as the "golden dollar") is a United States dollar coin introduced in 2000, but subsequently minted only for niche circulation from 2002 onward. The coin generally failed to meet consumer and business demands. It is still generally accepted in circulation.
  
  These coins have a copper core clad by manganese brass, giving them a distinctive golden color. The coin features an obverse by Glenna Goodacre. From 2000 to 2008, the reverse featured an eagle design by Thomas D. Rogers. Since 2009, the reverse of the Sacagawea dollar has been changed yearly, with each design in the series depicting a different aspect of Native American cultures. These coins are marketed as "Native American dollars". (Full article...)

  The Hudson, New York, Sesquicentennial half dollar, sometimes called the Hudson Sesquicentennial half dollar, is a commemorative fifty-cent piece struck by the United States Bureau of the Mint in 1935. The coin was designed by Chester Beach. Its obverse depicts the Half Moon, flagship of Henry Hudson, after whom the city of Hudson, New York is named. In addition to showing the ship, the coin displays a version of the Hudson city seal, with Neptune riding a whale, a design that has drawn commentary over the years.
  
  Although the city of Hudson was a relatively small municipality, legislation to issue a coin in honor of its 150th anniversary went through Congress without opposition and was signed by President Franklin D. Roosevelt, becoming the Act of May 2, 1935. In June 1935, 10,000 Hudson half dollars were distributed to civic authorities for sale to the public. (Full article...)

  Fifty-cent fractional currency depicting Francis E. Spinner, with autograph signature.

  
  Fractional currency, also referred to as shinplasters, was introduced by the United States federal government following the outbreak of the Civil War. These low-denomination banknotes of the United States dollar were in use between 21 August 1862 and 15 February 1876, and issued in denominations of 3, 5, 10, 15, 25, and 50 cents across five issuing periods. The complete type set below is part of the National Numismatic Collection, housed at the National Museum of American History, part of the Smithsonian Institution. (Full article...)

  The Liberty Head nickel, sometimes referred to as the V nickel because of its reverse (or tails) design, is an American five-cent piece. It was struck for circulation from 1883 until 1912, with at least five pieces being surreptitiously struck dated 1913. The obverse features a left-facing image of the goddess of Liberty.
  
  The original copper–nickel five-cent piece, the Shield nickel, had longstanding production problems, and in the early 1880s, the United States Mint was looking to replace it. Mint Chief Engraver Charles Barber was instructed to prepare designs for proposed one-, three-, and five-cent pieces, which were to bear similar designs. Only the new five-cent piece was approved, and went into production in 1883. For almost thirty years large quantities of coin of this design were produced to meet commercial demand, especially as coin-operated machines became increasingly popular. (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 British florin, or two-shilling piece (2/– or 2s.), was a coin worth 1⁄10 of one pound, or 24 pence. It was issued from 1849 until 1967, with a final issue for collectors dated 1970. It was the last coin circulating immediately prior to decimalisation to be demonetised, in 1993, having for a quarter of a century circulated alongside the ten-pence piece, identical in specifications and value.
  
  The florin was introduced as part of an experiment in decimalisation that went no further at the time. The original florins, dated 1849, attracted controversy for omitting a reference to God from Queen Victoria's titles; that type is accordingly known as the "Godless florin", and was in 1851 succeeded by the "Gothic florin", for its design and style of lettering. Throughout most of its existence, the florin bore some variation of either the shields of the United Kingdom, or the emblems of its constituent nations on the reverse, a tradition broken between 1902 and 1910, when the coin featured a windswept figure of a standing Britannia.

  The Fort Vancouver Centennial half dollar, sometimes called the Fort Vancouver half dollar, is a commemorative fifty-cent piece struck by the United States Bureau of the Mint in 1925. The coin was designed by Laura Gardin Fraser. Its obverse depicts John McLoughlin, who was in charge of Fort Vancouver (present-day Vancouver, Washington) from its construction in 1825 until 1846. From there, he effectively ruled the Oregon Country on behalf of the Hudson's Bay Company. The reverse shows an armed frontiersman standing in front of the fort.
  
  Washington Representative Albert Johnson wanted a coin for Fort Vancouver's centennial celebrations, but was persuaded to accept a medal instead. But when another congressman was successful in amending a coinage bill to add a commemorative, Johnson tacked on language authorizing a coin for Fort Vancouver. The Senate agreed to the changes, and President Calvin Coolidge signed the authorizing act on February 24, 1925. (Full article...)

  The Grant Memorial coinage are a gold dollar and silver half dollar struck by the United States Bureau of the Mint in 1922 in honor of the 100th anniversary of the birth of Ulysses S. Grant, a leading Union general during the American Civil War and later the 18th president of the United States. The two coins, identical in design and sculpted by Laura Gardin Fraser, portrayed Grant on the obverse and his birthplace in Ohio on the reverse.
  
  The Ulysses S. Grant Centenary Memorial Association, also called the Grant Commission, wanted to sell 200,000 gold dollars to be able to finance multiple projects in the areas of Grant's birthplace and boyhood home. Congress authorized only 10,000 gold coins, but also authorized 250,000 half dollars. Hoping to boost sales, the Grant Commission asked for 5,000 of the gold dollars to bear a special mark, an incuse star; the Mint did the same for the half dollars as well, unasked for.

  The Washington quarter is the present quarter dollar or 25-cent piece issued by the United States Mint. The coin was first struck in 1932; the original version was designed by sculptor John Flanagan.
  
  As the United States prepared to celebrate the 1932 bicentennial of the birth of its first president, George Washington, members of the bicentennial committee established by Congress sought a Washington half dollar. They wanted to displace for that year only the regular issue Walking Liberty half dollar; instead Congress permanently replaced the Standing Liberty quarter, requiring that a depiction of Washington appear on the obverse of the new coin. The committee had engaged sculptor Laura Gardin Fraser to design a commemorative medal, and wanted her to adapt her design for the quarter. Although Fraser's work was supported by the Commission of Fine Arts and its chairman, Charles W. Moore, Treasury Secretary Andrew W. Mellon chose a design by Flanagan, and Mellon's successor, Ogden L. Mills, refused to disturb the decision. (Full article...)

  The Pilgrim Tercentenary half dollar or Pilgrim half dollar was a commemorative fifty-cent coin struck by the United States Bureau of the Mint in 1920 and 1921 to mark the 300th anniversary (tercentenary) of the arrival of the Pilgrims in North America. It was designed by Cyrus E. Dallin.
  
  Massachusetts Congressman Joseph Walsh was involved in joint federal and state efforts to mark the anniversary. He saw a reference to a proposed Maine Centennial half dollar and realized that a coin could be issued for the Pilgrim anniversary in support of the observances at Plymouth, Massachusetts. The bill moved quickly through the legislative process and became the Act of May 12, 1920. (Full article...)

Two golden 20 kr coins from the Scandinavian Monetary Union, which was based on a gold standard. The coin to the left is Swedish and the one on the right is Danish.

A gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971 when the United States unilaterally terminated convertibility of the US dollar to gold, effectively ending the Bretton Woods system. Many states nonetheless hold substantial gold reserves.

Historically, the silver standard and bimetallism have been more common than the gold standard. The shift to an international monetary system based on a gold standard reflected accident, network externalities, and path dependence. Great Britain accidentally adopted a de facto gold standard in 1717 when Sir Isaac Newton, then-master of the Royal Mint, set the exchange rate of silver to gold too low, thus causing silver coins to go out of circulation. As Great Britain became the world's leading financial and commercial power in the 19th century, other states increasingly adopted Britain's monetary system. (Full article...)

The Krugerrand (/ˈkruːɡərænd/; Afrikaans: [ˈkry.ərˌrant]) is a South African coin, first minted on 3 July 1967 to help market South African gold and produced by Rand Refinery and the South African Mint. The name is a compound of Paul Kruger, the former President of the South African Republic (depicted on the obverse), and rand, the South African unit of currency. On the reverse side of the Krugerrand is a pronking springbok, South Africa's national animal.

By 1980, the Krugerrand accounted for more than 90% of the global gold coin market and was the number one choice for investors buying gold. However, during the 1980s and 1990s, Krugerrands fell out of favor as some Western countries forbade import of the Krugerrand because of its association with the apartheid government of South Africa.
