The Numismatics Portal
Numismatics is the study or collection of currency, including coins, tokens, paper money, medals, and related objects. Experts of this study, 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.[dubious – discuss] Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems.

![Image 1The 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. Lyman W. Hoffecker [gl] 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.

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 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 (CFA) 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 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.

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 August 21, 1862, and February 15, 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 Louisiana Purchase Sesquicentennial half dollar was a proposed United States commemorative coin, legislation for which passed both houses of Congress, but was vetoed in 1954 by President Dwight Eisenhower. Intended to celebrate the 150th anniversary of the Louisiana Purchase (1803), the coin was lobbied for by both the Missouri Historical Society (MHS) and the Louisiana Purchase 150th Anniversary Association of New Orleans, who hoped to be able to buy the entire coin issue from the government and sell it at a profit.
Numismatist Eric P. Newman led the MHS's efforts, and corresponded with Congressman Thomas B. Curtis of Missouri, who helped push the bill forward with officials of the Louisiana group, such as Clay Shaw. Although many commemorative coins had been authorized by Congress in the 1930s, legislators passed few after that; the Treasury Department was strongly against their issue. When the House of Representatives held a hearing on the Louisiana Purchase Sesquicentennial half dollar, the bill was opposed by assistant director of the Mint F. Leland Howard. The House passed the bill in April 1953, but the Senate was slow to act, passing it in January 1954, and after the House concurred with the Senate amendments, the bill was sent to Eisenhower later that month.

The California Pacific International Exposition half dollar, sometimes called the California Pacific half dollar or the San Diego half dollar, is a commemorative fifty-cent piece struck by the United States Bureau of the Mint in 1935 and 1936. Robert Ingersoll Aitken designed the coin. Its obverse depicts Minerva and other elements of the Seal of California; the reverse shows buildings from the California Pacific International Exposition (held 1935–1936), which the coin was issued to honor.
Legislation for the half dollar moved through Congress without opposition in early 1935, and Aitken was hired to design it. Once his creation was approved, the San Francisco Mint produced 250,000 coins, but expected sales did not materialize. Left with more than 180,000 pieces they could not sell, the Exposition Commission went back to Congress for further legislation so it could return the unsold pieces and have new coins, dated 1936, hoping for greater sales in the second year of the fair's run. Although the commission was successful in getting the legislation passed, it was less so in selling the coins, and 150,000 1936-dated pieces were returned to the Mint. The coins, of either date, sell in the low hundreds of dollars today. (Full article...)
The Norfolk, Virginia, Bicentennial half dollar is a half dollar commemorative coin struck by the United States Bureau of the Mint in 1937, though it bears the date 1936. The coin commemorates the 200th anniversary of Norfolk being designated as a royal borough, and the 100th anniversary of it becoming a city. It was designed by spouses William Marks Simpson and Marjory Emory Simpson.
Virginia Senator Carter Glass sought legislation for a Norfolk half dollar, but the bill was amended in committee to provide for commemorative medals instead. Unaware of the change, Glass and the bill's sponsor in the House of Representatives, Absalom W. Robertson, shepherded the legislation through Congress. Local authorities in Norfolk did not want medals, and sought an amendment, which passed Congress in June 1937. (Full article...)
The double florin, or four-shilling piece, was a British coin produced by the Royal Mint between 1887 and 1890. One of the shortest-lived of all British coin denominations, it was struck in only four years. Its obverse, designed by Joseph Boehm and engraved by Leonard Charles Wyon, depicts Queen Victoria, whilst the reverse, featuring national symbols of the United Kingdom, was designed by Wyon based on the coinage of Charles II.
The double florin was introduced as part of a coinage redesign that took place in 1887, the year of Queen Victoria's Golden Jubilee. One purpose of the redesign was to replace portraits of the queen which had changed little since her youth, and which no longer resembled the monarch, who was nearing her seventieth birthday. Mint officials and politicians also sought to reduce dependence on the half sovereign, a gold coin worth ten shillings which was expensive to strike, by issuing the double florin (four shillings) and reintroducing the crown (five shillings) coin. They may also have intended a further decimalisation of the coinage after the introduction of the florin (two shillings, or one-tenth of a pound) in 1849. (Full article...)
The United States Assay Commission was an agency of the U.S. federal government from 1792 to 1980. Its function was to supervise the annual testing of the gold, silver, and (in its final years) base metal coins produced by the United States Mint to ensure that they met specifications. Although some members were designated by statute, for the most part the commission, which was freshly appointed each year, consisted of prominent Americans, including numismatists. Appointment to the Assay Commission was eagerly sought after, in part because commissioners received a commemorative medal. These medals, different each year, are extremely rare, with the exception of the 1977 issue, which was sold to the general public.
The Mint Act of 1792 authorized the Assay Commission. Beginning in 1797, it met in most years at the Philadelphia Mint. Each year, the president appointed unpaid members, who would gather in Philadelphia to ensure the weight and fineness of silver and gold coins issued the previous year were to specifications. In 1971, the commission met, but for the first time had no gold or silver to test, with the end of silver coinage. Beginning in 1977, President Jimmy Carter appointed no members of the public to the commission, and in 1980, he signed legislation abolishing it. (Full article...)
The Buffalo nickel or Indian Head nickel is a copper–nickel five-cent piece that was struck by the United States Mint from 1913 to 1938. It was designed by sculptor James Earle Fraser.
As part of a drive to beautify the coinage, five denominations of US coins had received new designs between 1907 and 1909. In 1911, Taft administration officials decided to replace Charles E. Barber's Liberty Head design for the nickel, and they commissioned Fraser to do the work. They were impressed by Fraser's designs showing a Native American and an American bison. The designs were approved in 1912, but were delayed several months because of objections from the Hobbs Manufacturing Company, which made mechanisms to detect slugs in nickel-operated machines. The company was not satisfied by changes made in the coin by Fraser, and, in February 1913, Treasury Secretary Franklin MacVeagh decided to issue the coins despite the objections. (Full article...)
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 Morgan dollar is a United States dollar coin minted from 1878 to 1904, as well as 1921. It was minted again beginning in 2021 as a collectible. It was the first standard silver dollar minted since the passage of the Coinage Act of 1873, which ended the free coining of silver and the production of the previous design, the Seated Liberty dollar. It contained 412.5 Troy grains of 90% pure silver (or 371.25 Troy grains = 24.057 g; 0.7734 ozt of pure silver). The coin is named after its designer, United States Mint Assistant Engraver George T. Morgan. The obverse depicts a profile portrait representing Liberty, modeled by Anna Willess Williams, while the reverse depicts an eagle with wings outstretched. The mint mark, if present, appears on the reverse above between D and O in "Dollar".
The dollar was authorized by the Bland–Allison Act. Following the passage of the 1873 act, mining interests lobbied to restore free silver, which would require the Mint to accept all silver presented to it and return it, struck into coin. Instead, the Bland–Allison Act was passed, which required the Treasury to purchase between two and four million dollars' worth of silver at market value to be coined into dollars each month. In 1890, the Bland–Allison Act was repealed by the Sherman Silver Purchase Act, which required the Treasury to purchase 4,500,000 troy ounces (140,000 kg) of silver each month, but only required further silver dollar production for one year. This act, once again, was repealed in 1893. (Full article...)
The Gobrecht dollar, minted from 1836 to 1839, was the first silver dollar struck for circulation by the United States Mint after production of that denomination had been halted in 1806 (the last previous silver dollars were struck in 1804 but dated 1803). The coin was struck in small numbers to determine whether the reintroduced silver dollar would be well received by the public.
In 1835, Director of the United States Mint Samuel Moore resigned his post, and Robert M. Patterson assumed the position. Shortly after, Patterson began an attempt to redesign the nation's coinage. After Mint Chief Engraver William Kneass suffered a stroke later that year, Christian Gobrecht was hired as an engraver. On August 1, Patterson wrote a letter to Philadelphia artist Thomas Sully laying out his plans for the dollar coin. He also asked Titian Peale to create a design for the coin. Sully created an obverse design depicting a seated representation of Liberty and Peale a reverse depicting a soaring bald eagle, which were adapted into coin designs by Gobrecht. After the designs were created and trials struck, production of the working dies began in September 1836. (Full article...)
The Turban Head eagle, also known as the Capped Bust eagle, was a ten-dollar gold piece, or eagle, struck by the United States Mint from 1795 to 1804. The piece was designed by Robert Scot, and was the first in the eagle series, which continued until the Mint ceased striking gold coins for circulation in 1933. The common name is a misnomer; Liberty does not wear a turban but a cap, believed by some to be a pileus or Phrygian cap (Liberty cap): her hair twisting around the headgear makes it resemble a turban.
The eagle was the largest denomination authorized by the Mint Act of 1792, which established the Bureau of the Mint. It was not struck until 1795, as the Mint at first struck copper and silver coins. The number of stars on the obverse was initially intended to be equal to the number of states in the Union, but with the number at 16, that idea was abandoned in favor of using 13 stars in honor of the original states. The initial reverse, featuring an eagle with a wreath in its mouth, proved unpopular and was replaced by a heraldic eagle. (Full article...)

The West Point Mint is a U.S. Mint production and depository facility erected in 1937 near the U.S. Military Academy in West Point, New York. As of July 2025, the facility held 54,067,331 troy ounces (1,681,682.0 kg) fine gold (over $183 billion USD as of August, 2025). As of 2019[update], 54 million troy ounces represented 22% of the United States' gold reserves. The mint at West Point is second only to the gold reserves held in secure storage at Fort Knox. Originally, the West Point Mint was called the West Point Bullion Depository. At one point it had the highest concentration of silver of any U.S. mint facility, and for 12 years produced circulating Lincoln cents. It has since minted mostly commemorative coins and stored gold.
It gained official status as a branch of the United States Mint on March 31, 1988. Later that year it was listed on the National Register of Historic Places. (Full article...)

The Queen's Beasts coins are British coins issued by the Royal Mint in platinum, gold, and silver since 2016. Each of the 10 beast coins in the series features a stylized version of one of the heraldic Queen's Beasts statues present at the coronation of Queen Elizabeth II representing her royal line of ancestry. The silver coin is notable as the first two-ounce United Kingdom silver bullion coin. Engraver Jody Clark designed the entire series. In December 2016, a full line of proof-quality coins was announced. In 2017, the mint began producing a platinum version of the coin. In April 2021, the Royal Mint issued an eleventh "Completer Coin" that featured all 10 of the Queen's Beasts, taking the series to 11 coins in total. The April 2021 release included a "one of a kind" gold coin weighing 10 kg and a denominated value of £10,000. Based upon the UK spot price at the time of release, the 10 kg gold coin had an intrinsic scrap value of approximately £411,000. It was widely reported that the 10 kg gold coin was the heaviest gold coin the Royal Mint had ever produced and that it had taken 400 hours to produce, four days to polish and has been described as a "Masterwork". The Royal Mint announced that Completer Coin completes the Queen's Beasts commemorative collection.
Single coins were delivered in a plastic coin capsule or flip, as chosen when ordering. Bulk orders were delivered in the same containers used for packaging Britannia bullion coins: 10 coins per tube, 20 tubes per box. The tube for silver can potentially hold a total of 14 coins. Proof coins were typically delivered in a coin capsule along with a display box and a booklet explaining the beast's significance in heraldic art. (Full article...)
