The silver value of a 50-cent piece, or half dollar, depends entirely on the year it was minted, which determines its metallic composition.
Based on the provided information, certain U.S. half dollars are composed of 90% silver. This composition applies to all half dollars minted for circulation in 1964 and earlier, such as the Franklin and Walking Liberty series, as well as the 1964 Kennedy half dollar. The specific monetary worth of the silver in these coins is known as their "melt value."
This melt value is not a fixed number; it fluctuates daily based on the current market spot price of silver. To calculate it, you would need to know the coin's silver weight and the current price of silver. A 90% silver half dollar contains approximately 0.36 troy ounces of pure silver.
It is important to distinguish these from later issues. Kennedy half dollars minted between 1965 and 1970 have a reduced silver content of 40%. Any half dollar intended for circulation minted from 1971 to the present contains no silver and is therefore only worth its face value of 50 cents. To find the current value, one must first identify the coin's year and then consult a resource that tracks the melt value based on live metal prices.
