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.
The 1829 Curl base 2 is an extremely rare and much sought after variety. In 25 years, PCGS has only graded a couple of dozen examples, and so far the highest graded was VF35. This coin probably does not exist in Mint State and may not even exist in AU (Almost Uncirculated 50-58) or even EF (Extremely Fine 40-45)!!!!!!

Louis Scuderi wrote in the January 2012 edition (#70) of the JR Newsletter that he knew of at least 40 confirmed/documented examples of this rare die variety. Most of the new examples are in low grade and several have shown up unattributed on eBay.
