The Kennedy Half Dollar is a 50-cent coin issued by the United States Mint, first minted in 1964 to honor President John F. Kennedy following his assassination. The 2012 Kennedy Half Dollar is part of a series that has seen various design modifications over the years but maintains the original obverse portrait of Kennedy, designed by Gilroy Roberts, and a reverse featuring the Presidential Seal by Frank Gasparro. The coin is composed of an outer layer of 75% copper and 25% nickel, with a core of pure copper in the circulating versions, and is sought after by collectors for its historical significance and varying mintage figures.
