The Kennedy Half Dollar, designed by Gilroy Roberts and Frank Gasparro, began its mintage in 1964 and continues to be struck to this day. This specific Kennedy Half Dollar was struck at the San Francisco Mint in 1978 and has been graded in  perfect  Proof  70  Ultra Cameo condition. Out of every 1978-S Proof Kennedy Half Dollar struck by the US Mint, significantly less than 1% have been graded in Proof  70  UCAM condition.  To add to the rarity of these stunning  Kennedy Half Dollars, each has been given Rick Tomaska's Everest seal of approval. Only coins that Rick Tomaska himself has inspected and deemed to exhibit the highest cameo contrast receive Everest certification. With such a low Proof 70 Ultra Cameo population, this coin is a Condition Rarity.
