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):
In terms of population rarity, i.e. the total number of specimens known, the 1891-CC is the third rarest Carson City Mint Double Eagle after the 1870-CC and 1871-CC. It is more rare than the 1878-CC or 1879-CC except in high grade, and it is much rarer than the 1885-CC in any condition. The majority of 1891-CC Double Eagles are EF or AU and all of then are semi-prooflike or prooflike. In average uncirculated condition (MS-60), the 1891-CC is very rare and relatively few are known. There are several choice uncs in existence but I have never personally seen a gem specimen.
