The intrinsic value of a United States silver half dollar is primarily determined by its year of mintage, as this dictates the coin's specific silver content. There are two principal categories of silver half dollars based on their metallic composition, and their values differ accordingly. The base value for a common, circulated coin is its "melt value," which fluctuates daily with the market price of silver.
Half dollars minted in 1964 or earlier are composed of 90% silver. This group includes several series: the Barber (1892-1915), the Walking Liberty (1916-1947), the Franklin (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 $29.53 per troy ounce, the melt value for a 90% silver half dollar is approximately $10.68. This figure represents the coin's fundamental bullion worth.
Following the Coinage Act of 1965, the composition of the half dollar was altered. Kennedy half dollars produced from 1965 through 1970 contain a reduced silver content of 40%. These coins have a total silver weight of approximately 0.1479 troy ounces. Consequently, their intrinsic value is lower than that of the earlier 90% silver issues. Using the same market price for silver, the melt value of a 40% silver half dollar is approximately $4.37.
It is crucial to understand that these valuations are based solely on the intrinsic silver content of the coins. The actual market value of a specific half dollar can be significantly higher if it holds numismatic value. Factors such as the coin's rarity, date, mint mark, and physical condition can add a substantial premium for collectors, far exceeding its melt value. Therefore, while the silver content provides a reliable baseline, a comprehensive valuation must also consider the coin's status as a collectible.
