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.
David Akers (1975/88):
I would estimate that no more than half the original mintage of 20 pieces still exists in unimpaired state. Impaired proofs are readily identifiable from business strikes by the significant difference in the position of the date. On the proofs, the date is high in the field and the 5 nearly touches the bust. On the business strikes, however, the date is lower in the field and the 5 is distant from the bust. The Ullmer coin and the Wolfson coin were both erroneously catalogued as proofs when they were, in fact, business strikes.
