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.

Ron Guth:

1820 Half Dollars offer the collector a dizzzying array of possibilities: Large Date, Small Date, Overdate, Square Base 2, Curl Base 2, Knob 2, Plain 2, No serifs on E, and combinations of the preceding. In this case, we have an 1820 Half Dollar with a Square Base 2, a Large Date, and a Knob 2. Jse the image above to determine the proper variety.

According to the PCGS Population Report (as of September 2011), the 1820 Square Base 2, Large Date, Knob 2 is less common than the Curl Base 2, Small Date and the Square Base 2, Large Date, No Knob, but not as scarce as the 1820/19 Square Base 2 and the 1820/19 Curl Base 2.

Mint State examples of the 1820 Square Base 2, Large Date, Knob 2 Half Dollar are very scarce and the finest example certified by PCGS is a single MS-66.
