All U.S. coins are produced by the U.S. Department of the Treasury through the U.S. Mint.
People in the US have been using nickel coins since 1866 (still in use today).
The US Mint produced 3.548 billion circulating coins in 2009. 2.354 Billion of those were pennies.
Today in currently circulating coins produced in 2013 there are a number of different metals used. Copper and nickel are used for the nickel, dime, quarter and half dollar. Copper plated zinc is used for the penny and a special alloy of brass is used for the dollar coin. However, silver, gold and platinum are used for commemorative and bullion coins which do not circulate.
Coins struck for circulation in the US today have no silver in them.
All U.S. coins and currency are produced in the United States.
Platinum Bullion coins are produced at the Philadelphia Mint and West Point Mint.
American coins have always been produced by the US Mint, a division of the Treasury. There are currently 4 mints, with different roles (although there may be some exceptions depending on the year): > Philadelphia and Denver make coins for circulation > San Francisco makes proof coins for collectors > West Point makes bullion and commemorative coins for investors and collectors. Other mints have been located in New Orleans, Carson City, Charlotte, and Dahlonega GA. Popular misunderstanding to the contrary, bills (paper money) are NOT made by the Mint. They're produced by the Bureau of Engraving and Printing, which is a separate department.
For coins used every day the 1 dollar coin is the largest today , when gold coins were used the $20.00 double eagle was the largest. But the $100.00 platinum bullion coins are the highest denomination ever made by the US.
Because without coins then none of us would have any cents or maybe not
The US had 20 dollar gold coins and also 10, 5, 2 1/2 and 1 dollar gold coins.
A 1955 US Mint set contained 22 coins. It had 2 coins from each Mint that produced coins for circulation. All US Mint sets from 1947 through 1958 are double sets.
No. The US Mint in San Francisco has produced many coins for circulation since it opened in 1854. Prior to 1968 nearly all proof coins were made at the US Mint in Philadelphia, Pennsylvania. Beginning in 1968, all proof coins were produced at the US Mint in San Francisco although this mint continued to produce Lincoln Cents for circulation until 1974 and Jefferson nickels until 1971. In 1984 the US Mint at West Point, New York began minting proof coins as well. The Philadelphia Mint also produced proof $1 coins in 1999.
