Many U.S. coins that were one time in circulation are worth more than their face value. Always save U.S. coins that are more than a century old, and learn which younger coins are worth saving as well.
All Lincoln wheat cents, including the common dates, are worth saving. The rarest dates are the 1909-S, 1909-S VDB , 1914-D and 1931-S.
Buffalo nickels are always worth saving, but there are also some valuable Jefferson nickels. Save the nickels from late 1930s, the 1950-D and silver war nickels.
Dimes, quarters and half dollars from 1964 and earlier are made of 90 percent silver. Half dollars from 1965 to 1969 are made of 40 percent silver.
All silver dollars are worth saving. The U.S. Mint made large silver dollars off and on until 1935.
Other Dollar Coins
The Eisenhower dollars made in the 1970s are worth saving; however, the standard issue coins that went into circulation are not silver.
