The value of a U.S. half dollar today depends almost entirely on its date, mint mark, and condition. While modern half dollars are typically worth their face value of 50 cents, older coins can be worth significantly more due to their silver content and numismatic, or collector, value.
Half dollars minted from 1971 to the present are made of a copper-nickel clad composition and are generally worth only 50 cents if they are in circulated condition. However, half dollars minted before this period contain silver, giving them a "melt value" based on the current price of silver.
Specifically, Kennedy half dollars from 1964 are composed of 90% silver, making their base value much higher than 50 cents. Kennedy half dollars from 1965 to 1970 contain 40% silver and are also worth more than face value. Other series, such as the Franklin half dollar (1948-1963) and the Walking Liberty half dollar (1916-1947), are also made of 90% silver. The value for these silver coins is at least their worth in silver, which fluctuates daily.
Beyond silver content, a half dollar's value can increase substantially based on its rarity and condition. A coin's specific year and mint mark can make it a key date sought after by collectors. A coin in pristine, uncirculated condition will always command a higher price than a heavily worn one of the same type. For an exact valuation, a specific coin must be assessed by a professional or compared against a detailed price guide that lists values by issue and grade.
