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 Series

The 1809 "Circle in 0" Half Cent variety was created when a larger 0 was punched over a smaller 0 in the date. The initial 0 must have been from a punch intended for the Half Eagle (the 0's on the Dime and Quarter Eagle were too small), and both the Half Cent and the Half Eagle share similar shaped 9's. While not a particularly rare variety, this issue is very difficult to find in high circulated grades and is nearly impossible to find in Mint State.
