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 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):
The 1905 is the rarest 20th Century Liberty Head Double Eagle. It is much rarer than the lower mintage 1902 or the 1906 and it is also more rare in all grades, including Unc., than the underrated 1901-S, 1902-S and 1905-S. In terms of overall rarity, the 1905 is similar to the 1888, 1889 and 1898 but it may well be more rare than any of those three dates in full mint state. I consider the 1905 to be very scarce in Unc-60 condition and rare in choice Unc. Only a few gems are reported (I have not personally seen one, though) and so the 1905 must be rated as very rare at the MS-65 level.
