The Kennedy Half Dollar began mintage in 1964 and is still struck to this day. This set includes 3 examples struck from 1968 to 1970, each graded in Proof 69 Ultra Cameo condition. To add to the rarity of these stunning coins, they have been housed in Rick Tomaska's exclusive Signature series holder. 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. Each of these 3 Kennedy Half Dollars have populations under 1% of their respective mintages, and Tomaska Signature Series populations under 25 examples! With such low populations, every single coin in this set is considered a Condition Rarity. No examples from these issues have been graded in PF70 condition, making these the finest known of their issue.
