how much silver is in a 1967 half dollar

[MariaMarie]

Based on numismatic and metallurgical data, a 1967 Kennedy half dollar possesses a silver content of 40%. This specific composition was a result of the Coinage Act of 1965, which sought to reduce the amount of silver in United States coinage due to rising silver prices.

The coin is constructed using a clad method. It features outer layers composed of 80% silver and 20% copper, which are bonded to an inner core of 20.9% silver and 79.1% copper. This layered structure results in an overall metallic composition of 40% silver and 60% copper for the entire coin.

In terms of specific mass, a 1967 half dollar has a total weight of 11.5 grams. Given its 40% silver content, the actual amount of pure silver contained within the coin is 4.6 grams, which is equivalent to approximately 0.1479 troy ounces. This silver content distinguishes it from half dollars minted in 1964 and earlier, which were 90% silver, and those minted from 1971 onward, which contain no silver.
