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.

Ron Guth: Most (perhaps all) examples of this date utilize an Old Reverse ("Hub of 1840-1858"). Please report any New Reverse examples.

David Akers (1975/88): As the mintage would indicate, the 1866-S is more common than the previous S mints of the 1860's. However, the vast majority are well worn (VF or less) and, in fact, the 1866-S is tied for having the fourth lowest average grade of any quarter eagle in our 226 catalogue auction survey. As is the case with all early S Mint quarter eagles, the 1866-S is grossly underrated in high grade. Strictly uncirculated specimens are extremely rare. I have seen three or four Uncs. of this date, but no more.
