The Kennedy half dollar minted in 1974, while bearing the same design as those containing silver in previous years, is primarily composed of copper and nickel. This composition distinguishes it from the earlier versions of the coin which possessed a silver content of 90% (prior to 1965) or 40% (from 1965 to 1970). Therefore, the 1974 issue lacks the precious metal component present in its predecessors.
The significance of the 1974 half dollar lies in its place within the broader history of US coinage. It represents a period where the rising cost of silver necessitated a shift to base metal compositions for circulating currency. Despite not containing silver, these coins remain collectible due to their historical context and the overall popularity of the Kennedy half dollar series. Their value primarily derives from numismatic interest and their condition, rather than their intrinsic metal content.
