The weight and composition of a silver half dollar depend on the specific year it was minted. The provided information highlights the Kennedy Half Dollar series as a primary example of this variation.
A 1964 Kennedy Half Dollar, which is composed of 90% silver, contains 0.3617 troy ounces of pure silver. Following that initial year, the silver content was reduced. From 1965 through 1970, Kennedy half dollars were made with 40% silver. Most modern Kennedy half dollars produced for circulation do not contain any silver, further underscoring that the year of issue is the critical factor in determining the coin's metallic weight and composition.
