1964 was the last year the U.S. stopped minting coins in solid silver. However, there was a series of coins that were sandwiched in silver and maybe an expert coin collector will come on here and cover all those coins and different years they were stamped.
Dimes, Quarters, half dollars, and dollar coins before 1964 are 90% silver. Also half dollars from 1965-1969 have 40% silver in them. Silver nickels were minted during 1942-1945 and the nickels are only 35% silver. Any other nickels other than those dates aren't silver. Source(s): Have about 5 years experience.
