Based on the provided information, a 1962 Franklin half dollar is composed of 90% silver.
This particular coin hails from an era in American history when many U.S. coins intended for circulation contained a high intrinsic value derived from their precious metal content. The 1962 issue is a prime example of this standard.
The Franklin half dollar series was one of the last to be minted with this 90% silver composition for public circulation. The practice of using such a high silver content for circulating coinage came to an end shortly after the series was retired in 1963, making these coins sought after for their metallic value as well as their numismatic interest. A standard 90% silver half dollar of this period contains approximately 0.36169 troy ounces of pure silver.
