What is the Precious Metal Weight of a Silver Quarter?
Have you heard the term coin silver or seen it used in the context of precious metals or coin collecting? Coin silver is a silver-copper alloy made from 90% silver and 10% copper produced before the Coinage Act of 1965.
Before 1965, United States quarters were comprised of 90% silver and 10% copper. These quarters weigh 6.25 grams and contain about 5.63 grams of silver per coin.
How Many Silver Quarters Add Up to One Ounce of Silver?
Pre-1965 90% junk silver quarters contain 0.17875 ounces of silver per coin. To compile a full troy ounce of silver, you would need about 5.5 Pre-1965 U.S. Quarters. Since we don’t commonly cut quarters in half, we will round that up to six.
What is the Composition of Today’s Quarters?
With the passing of the Coinage Act of 1965, silver was no longer used in U.S. quarters or dimes as the silver value exceeded the coins face value.
This act changed the composition of American quarters to 91.67% copper and 8.33% nickel and this mixture of metals is still used for American coins today.
