The 1952 Proof Franklin Half Dollar is one of the scarcer issues in the series. It is also the third lowest mintage from the Proof Franklin Half Dollar series. It is fairly common in grades up to about PR65. Anything higher becomes even scarcer.
With Cameo surfaces it is very hard to find in any grade and anything above PR65 Cameo is very scarce. Examples above PR65 condition usually command a significant premium.
With Deep Cameo surfaces it is almost unheard of and very few examples are confirmed in all grades combined. Expect to pay a huge premium for any example containing Deep Cameo surfaces.
