Coins of the United States dollar were first minted in 1792. New coins have been produced annually and they make up a valuable aspect of the United States currency system. Today, circulating coins exist in denominations of 1¢, 5¢, 10¢, 25¢, 50¢, and $1.00. Also minted are bullion and commemorative coins. All of these are produced by the United States Mint. The coins are then sold to Federal Reserve Banks which in turn are responsible for putting coins into circulation and withdrawing them as demanded by the country's economy.
A nickel is a five-cent coin struck by the United States Mint. Composed of cupronickel, the piece has been issued since 1866. Its diameter is 0.835 inches (21.21 mm) and its thickness is 0.077 inches (1.95 mm).
The dime, in United States usage, is a ten-cent coin, one tenth of a United States dollar, labeled formally as "one dime". The denomination was first authorized by the Coinage Act of 1792.
The United States Mint has minted numerous commemorative coins to commemorate persons, places, events, and institutions since 1848. Many of these coins are not intended for general circulation, but are still legal tender. The mint also produces commemorative medals, which are similar to coins but do not have a face value, and therefore are not legal tender.
The dollar coin is a United States coin with a face value of one United States dollar. Dollar coins have been minted in the United States in gold, silver, and base metal versions. Dollar coins were first minted in the United States in 1794.
A double eagle is a gold coin of the United States with a denomination of $20. The coins are 34 mm x 2 mm and are made from a 90% gold and 10% copper alloy and have a total weight of 1.0750 troy ounces.
The eagle was a United States $10 gold coin issued by the United States Mint from 1792 to 1933.
The Jamaican dollar has been the currency of Jamaica since 1969. It is often abbreviated to J$, the J serving to distinguish it from other dollar-denominated currencies. It is divided into 100 cents, although cent denominations are no longer in use as of 2018. Goods and services may still be priced in cents, but cash transactions are now rounded to the nearest dollar.
William Barber was the fifth Chief Engraver of the United States Mint from 1869 until his death. He succeeded James B. Longacre in the position.
Charles Edward Barber was an American coin engraver who served as the sixth chief engraver of the United States Mint from 1879 until his death in 1917. He had a long and fruitful career in coinage, designing most of the coins produced at the mint during his time as chief engraver. He did full coin designs, and he designed about 30 medals in his lifetime. The Barber coinage were named after him. In addition, Barber designed a number of commemorative coins, some in partnership with assistant engraver George T. Morgan. For the popular Columbian half dollar, and the Panama-Pacific half dollar and quarter eagle, Barber designed the obverse and Morgan the reverse. Barber also designed the 1883 coins for the Kingdom of Hawaii, and also Cuban coinage of 1915. Barber's design on the Cuba 5 centavo coin remained in use until 1961.
A pattern coin is a coin which has not been approved for release, but produced to evaluate a proposed coin design. They are often off-metal strike, to proof standard or piedforts. Many coin collectors collect and study pattern coins because of their historical importance. Many of the world's most valuable coins are pattern coins; nearly 25 of the pieces listed in 100 Greatest US Coins are pattern coins.
The Indian Head cent, also known as an Indian Head penny, was a one-cent coin ($0.01) produced by the United States Bureau of the Mint from 1859 to 1909. It was designed by James Barton Longacre, the Chief Engraver at the Philadelphia Mint.
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.
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.
The half eagle is a United States coin that was produced for circulation from 1795 to 1929 and in commemorative and bullion coins since 1983. Composed almost entirely of gold, its face value of five dollars is half that of the eagle coin. Production of the half eagle was authorized by the Coinage Act of 1792, and it was the first gold coin minted by the United States.
The coins of the Australian dollar were introduced on 14 February 1966, although they did not at that time include the one-dollar or two-dollar coins. The dollar was equivalent in value to 10 shillings in the former currency.
The numismatic history of the United States began with Colonial coins such as the pine tree shilling and paper money; most notably the foreign but widely accepted Spanish piece of eight, ultimately descended from the Joachimsthaler and the direct ancestor of the U.S. Dollar.
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 five Panama–Pacific commemorative coins were produced in connection with the 1915 Panama–Pacific International Exposition in San Francisco. Struck at that city's mint, the issue included round and octagonal $50 pieces. Excepting modern bullion coins, these two gold pieces are the highest denomination ever issued and the largest coins ever struck by the United States Mint. The octagonal $50 piece is the only U.S. coin to be issued that is not round.
The Union was a proposed $100 coin of the United States dollar. It was canceled before any pattern coins could be minted.
