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:

The 1866-S Dime is a low-mintage date relative to other series, but the mintage is typical of S-Mint Dimes from the early to mid-1860s, and a very high mintage compared to the 1866-P (135,000 to 8,000, respectively). Based on the mintages alone, price guides have always presented a higher value for the lower mintage 166-P. However, the advent of Population Reports, after a 25+ year record of coin grading, show that the 1866-S is actually scarcer than the 1866-P in Mint State. In addition, the highest-graded 1866-S Dimes are two points less than the highest-graded 1866-P. For the 1866-S Dime, the best examples available to collectors are a pair of MS-65s, one of which is illustrated above.

Some examples show a wavy, vertical crack that nearly bisects the obverse.
