The value of a United States silver half dollar is primarily determined by its year of mintage, which dictates its metallic composition and, therefore, its intrinsic worth based on the current price of silver. The provided data indicates two distinct categories of silver half dollars circulated in the 20th century.
The first and more common category includes half dollars minted in 1964 and earlier. This group encompasses the Barber, Walking Liberty, Franklin, and the 1964 Kennedy half dollars. These coins are composed of 90% silver and contain 0.3617 troy ounces of the precious metal. Based on a silver spot price of $29.52 per troy ounce, the intrinsic silver melt value for one of these 90% silver coins is approximately $10.68.
The second category consists of Kennedy half dollars minted between the years 1965 and 1970. In an effort to reduce the amount of silver in circulation, the composition of these coins was changed to 40% silver. Each of these coins contains 0.1479 troy ounces of silver, giving them a lower melt value of approximately $4.37 at the same silver spot price.
It is essential to recognize that these values represent the coin's intrinsic bullion or "melt" value. The actual market value, or numismatic value, of a specific half dollar can be considerably higher. Factors such as the coin's condition, rarity, specific date, and mint mark play a significant role in its value to collectors. Therefore, while the melt value provides a fundamental baseline, it does not account for any potential premium a coin might carry due to its collectibility.
