Kennedy Half Dollars
The Kennedy Half Dollar is a fifty-cent US coin struck in memory of President John F. Kennedy, assassinated in 1963. It was minted from 1964 through 1970. The 1964 Kennedy Half Dollars were struck with 90% silver and 10% copper with a silver weight of 0.36169 troy ounces. Due to rises in bullion prices, the silver content was reduced to 40% from 1965 onward, equivalent to 0.1479 troy ounces.
The obverse features a profile of JFK while the reverse side sports a bald eagle clutching olive branches. The designs are the work of Gilroy Roberts and Frank Gasparro.
Although the Kennedy Half Dollar continues to be struck today by the US Mint, it has been produced with base metals since 1971 and is not worthy of coin collectors.
