The Sheldon Rarity Scale


A rarity may be listed as “unconfirmed” if we have not found conclusive evidence that a date or die marriage exists. An example is the 1873-S, which has a mintage record but no known examples. We also use this listing for die marriages which have been documented in previously published references but which we’ve been unable to confirm, either by direct examination or by reviewing auction records. Examples include our 1852 die marriages OC-2 and OC-P4.
