The metallic composition of the Franklin half dollar, specifically the amount of silver it contains, is a key attribute. Coins produced from 1948 to 1963 are comprised of 90% silver and 10% copper. This substantial precious metal component distinguishes them from circulating coinage of later eras. A typical coin of this type contains approximately 0.3617 troy ounces of pure silver.
The intrinsic value derived from the silver in these coins makes them attractive to collectors and investors alike. Fluctuations in the silver market directly impact the worth of these coins beyond their face value. Their historical context, representing a specific period in American coinage, further enhances their desirability and collectibility.
