The Survival Estimate represents an average of one or more experts' opinions as to how many examples survive of a particular coin in three categories: 1) all grades, 2) 60 or better, and 3) 65 or better. These estimates are based on a variety of sources, including population reports, auction appearances, and personal knowledge. Survival estimates include coins that are raw, certified by PCGS, and certified by other grading services.
Numismatic Rarity
Numismatic Rarity converts the Survival Estimate for a particular coin into a number from 1 to 10 (with decimal increments) based on the PCGS Rarity Scale. The higher the number, the more rare the coin.
Relative Rarity By Type
Relative Rarity By Type ranks the rarity of this coin with all other coins of this Type. Lower numbers indicate rarer coins.
Relative Rarity By Series
Relative Rarity By Series ranks the rarity of this coin with all other coins of this Series. Lower numbers indicate rarer coins.
The 1957 Proof Franklin Half Dollar is fairly common for a proof coin. In PR60 to about PR67 it is easy and inexpensive to obtain. In PR68 it becomes much scarcer and worth a significantly higher premium than PR67 examples. When displaying Cameo surfaces it is obviously scarcer than non Cameo examples. With enough searching a Cameo example can be purchased inexpensively up to about PR67 grade. Examples displaying Deep Cameo surfaces are very scarce with less than a few hundred examples known in all grades combined.
