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.
The US Dime and Quarter Dollar changed from 90% silver to 0% silver after 1964. The US Half Dollar went from 90% silver to 40% silver from 1965 through 1970 after that it contained 0% silver. The US Dollar had 90% silver until they stopped making them in 1935.
