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.
Early on, the silver coins had different percentages of silver than what we know of today. The half dime, which as the 5 cent coin of that period, contained 89.24% silver. The first dimes, quarters, half dollars and dollar coins of the time also contained 89.24% silver. This seemingly odd percentage of silver continued for these coins until 1837 for dimes, 1838 for quarters, 1836 for half dollars and 1837 for silver dollar coins. The change was mandated by The Law of January 18, 1837 to 412 1/2 grains in weight and .900 fineness.
