Rarity and Survival Estimates Learn More

Grades	Survival Estimate 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.

Jaime Hernandez:

The 1866 Proof Seated Liberty Dime is one of the easier dates to obtain in the series. It appears as if most examples exist in grades of PR62 - PR64. Examples in PR65 to PR66 are much scarcer. Any example grading PR67 is considered rare, as about a dozen or less exist in this condition. Anything above PR67 is extremely rare.
