Based on professional numismatic standards, the value of a 1964 Kennedy half dollar is determined by two primary factors: its silver content and its collectible condition.
The most significant factor for most 1964 half dollars is their composition. This coin was the last regular-issue U.S. half dollar to be struck in 90% silver. As a result, its fundamental value is tied to its silver bullion content, often referred to as its "melt value." This base value fluctuates daily with the market price of silver. A circulated 1964 half dollar, showing signs of wear from being used as money, is typically worth this intrinsic silver value.
Beyond its melt value, a 1964 half dollar can have a numismatic premium if it is in excellent condition. Coins that were never used in circulation and remain in their original Mint State (MS) condition are sought after by collectors. The value increases with the quality of the coin's preservation, which is formally assessed through a grading system. Coins in higher Mint State grades, such as MS-65 or above, can be worth considerably more than their silver content.
For a precise valuation, collectors and dealers refer to professional pricing resources like Greysheet and the NGC Price Guide, which provide market values based on the coin's specific grade. Therefore, while a common, circulated 1964 half dollar is valued based on its silver, a pristine, uncirculated example is valued as a collectible, with prices determined by its rarity in that high-grade condition.
