The value of a silver half dollar is determined by two primary factors: its intrinsic bullion value, derived from its silver content, and its numismatic or collectible value, which is based on rarity, condition, and demand. While the provided context focuses on the Kennedy series, the principles apply to all silver half dollars.
The most fundamental value for these coins comes from their silver content. United States half dollars minted in 1964 or earlier, which includes the Barber, Walking Liberty, Franklin, and the 1964 Kennedy half dollars, are composed of 90% silver. Their base value is therefore tied directly to the current market price of silver and is significantly higher than their 50-cent face value. From 1965 through 1970, Kennedy half dollars were produced with a 40% silver composition, making them valuable for their silver content as well, though less so than their 90% silver counterparts. Half dollars intended for circulation after 1970 do not contain silver.
Beyond bullion, numismatic value can make certain half dollars worth much more. This value is driven by factors such as low mintage numbers, specific mint marks (key dates), minting errors, and the coin's physical condition (grade). For example, in the Walking Liberty series (1916-1947), dates like the 1921 and 1921-D are highly sought after due to their rarity. Similarly, certain Franklin half dollars (1948-1963) with specific features, or Kennedy half dollars with errors or from special mint sets, command high premiums from collectors. The condition is paramount; a common-date coin in pristine, uncirculated condition can be worth substantially more than a rare date in poor, heavily circulated condition.
