The 1960-P Franklin Half Dollar is considered a semi key date. As it's mintage is somewhat low compared to most of the other coins in the series. All 1960's Franklin Half Dollars are scarce in high gem condition. Especially in MS66 grade or higher. There are less than a few hundred examples known in MS66 or higher. With Full Bell lines it is even scarcer in MS66 condition with less than 100 known. In MS67 it is almost unheard of but they do exist.
