This set the stage for the complete elimination of silver from our coinage by the end of 1964. Any United States dime, quarter, half dollar or dollar that is dated 1964 or earlier is made of 90% silver. In the dime series, all coins dated 1965 or later are clad coins and contain no silver at all. The value of these coins is tied directly to the price of silver. At $20 per ounce, 90% silver coins are worth about fourteen times their face value. A dime would be worth about $1.40, a quarter about $3.50, and a half dollar, about $6.00. At the same silver price of $20, 40% silver half dollars are worth approximately $2.50 each.
