The contemporary value of a United States silver half dollar is primarily contingent upon its year of mintage, which dictates its silver composition. The provided information delineates two principal categories of these coins based on their silver content, and their worth is fundamentally tied to the fluctuating spot price of silver.
The first category consists of half dollars minted in 1964 and earlier, which are composed of 90% silver. This group includes several historical series: the Barber Half Dollar (1892-1915), the Walking Liberty Half Dollar (1916-1947), the Franklin Half Dollar (1948-1963), and the 1964 Kennedy Half Dollar. Each of these coins contains approximately 0.3617 troy ounces of pure silver. Based on a silver spot price of $29.28 per ounce, the intrinsic metallic or "melt" value for one of these 90% silver half dollars is calculated to be $10.59.
A second, distinct category comprises Kennedy Half Dollars minted between 1965 and 1970. These coins have a reduced silver content of 40%. Each of these later-issue half dollars contains approximately 0.1479 troy ounces of silver. Consequently, their melt value is lower; using the same silver spot price of $29.28 per ounce, the melt value for a 40% silver half dollar is $4.33. It is important to recognize that these figures represent the baseline value derived from the precious metal content alone. The actual market value can be substantially higher for coins that are rare, possess key date and mint mark combinations, or are in superior states of preservation, as numismatic demand from collectors adds a premium above the intrinsic melt value.
