Coin Facts Rarity Scale™

The Coin Facts Rarity Scale™ can be used to compare overall rarity of a coin in all grades or rarity in certain grades. For example, for many coins listed in the PCGS Rare Coin Market Report™ the rarity estimate is given for all surviving specimens in all grades ("All"), all surviving specimens that grade 60 or better ("60ob"), and all surviving specimens grade 65 or better ("65ob").

The figures for the survival estimates from which the Coin Facts Rarity Scale™ ratings are derived represent the consensus opinion of the Coin Facts Board of Experts. Coin Facts maintains an internal data base of survival estimates for all United States coins. Members of the Coin Facts Board of Experts (which include many of the top rare coin experts of all-time) list their estimates of survival rates in this data base. The figures used in the PCGS Rare Coin Market Report represent the average of the experts’ opinions. Note that the "survival rating for every U.S. coin" is an ongoing project which has just been recently started. There are a few coins in this initial issue of the PCGS Rare Coin Market Report that already have survival ratings. More will be added in each new issue as the experts continue their work, and rarity ratings may even change as experts compare notes and make adjustments.

Have fun reviewing the experts’ ratings for your favorite coins!
