There are no two-dollar coins currently in circulation in the United States. However, there were two two-dollar coins minted in the past: the Liberty Head two-dollar coin, minted from 1875 to 1929, and the Peace dollar, minted from 1921 to 1935. These coins are also considered rare and may not be accepted by merchants.
If you have two-dollar bills or coins, it is best to check with the merchant before attempting to use them.
