how much silver in 1967 half dollar

[DeAdeline]

The 1967 Kennedy Half Dollar possesses a silver content of 40 percent. This composition represents a significant reduction from the 90 percent silver standard used for half dollars minted in 1964 and earlier.

The 40 percent silver content is achieved through a clad or layered structure. The coin's outer layers are composed of an alloy of 75% silver and 25% copper. These layers are bonded to an inner core that consists of 20.9% silver and 79.1% copper. This specific metallurgical structure results in the overall 40% silver composition.

Given the coin's total standard weight of 11.5 grams, the actual silver weight within a 1967 half dollar is 4.6 grams. This 40% silver composition was used for all Kennedy half dollars minted from 1965 through 1970, after which the denomination was switched to a copper-nickel clad composition for general circulation.
