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.
A Brief History of The US Silver Half Dollar. The production of silver half dollars in the United States started in the early 1790s. These pieces have a face value of $0.50; however, depending on the year the coin was minted, it may be worth much more than this. From 1790 to 1965 every single coin in the mint was made with 90% pure silver. From 1965 to 1970, this dropped to 40% silver. However, since 1970 the coins have been made without silver. The coins were particularly popular in the first half of the 20th century.
