The 1964 half dollar, a United States coin, contains a significant amount of the precious metal. Specifically, these coins are composed of 90% silver and 10% copper. This composition yields a total silver weight of 0.7234 troy ounces, or approximately 22.5 grams, in each coin.
The presence of silver in these coins is noteworthy due to its intrinsic value and historical significance. In the mid-20th century, silver was a common component of U.S. coinage. The decision to reduce or eliminate silver from coins, starting in 1965, makes the 1964 half dollar a sought-after item for collectors and those interested in precious metals. These coins represent a tangible link to a period when circulating currency held a substantial amount of precious metal.
