The 1963-P circulation strike Franklin Half Dollar has a significantly large mintage compared to most coins in the series. It's mintage of over 22 million coins makes it a common issue in the series. And it is common in all circulated grades up to MS63 condition. In MS64 to MS65 condition there are still tens of thousands of examples available and not scarce by any means. But examples in MS64 to MS65 do tend to carry a premium of at least double their melt values. In MS66 condition it now becomes really scarce with about 50 coins known and none being finer.
