Collectible coins, specifically the United States 50 cent coins known as Kennedy Half Dollars, mark a significant era in American numismatics. The 1968 issue, minted in San Francisco, is particularly notable as it was part of a transition period and features a portrayal of President John F. Kennedy, designed by Gilroy Roberts. The San Francisco mint produced both business strike and proof versions of the 1968 Kennedy Half Dollar, with the proof coins typically showcasing higher quality due to their minting process. Collectors often seek these coins for their historical significance and limited mintage.
