The Kennedy Half Dollar, designed by Frank Gasparro and Gilroy Roberts, began its mintage in 1964 and continues to be struck to this day. This set of two Kennedy Half Dollars includes both the Philadelphia and Denver first-year-of-issue examples in Mint State 67 condition housed in Rick Tomaska's exclusive Signature Series holders. These renowned holders are only given to Kennedy Half Dollars that Rick Tomaska has inspected and deemed to exhibit the highest quality luster and eye appeal for their date and grade. As the first year of issue for Kennedy Half Dollars, these are among the most highly sought-after examples in the series. Only 8  examples of the 1964-P Kennedy and 12  examples of the 1964-D Kennedy have been graded in MS67 condition and housed in Rick Tomaska's hand-signed holders, making each of these coins not only a Condition Rarity, but also among the finest known.
