A very original piece, both sides exhibit warm olive-gray outlines to the devices. The surfaces are otherwise silver-gray in sheen, and they are uncommonly smooth for a Buffalo Nickel that acquired 20 points of wear. A bold-looking EF that is worthy of a solid bid. This error as created in the same manner as the 1937-D 3-Legged Nickel, namely drastic die polishing that (partially) effaced one of the bison's forelegs. Bill Fivaz and J.T. Stanton (Cherrypickers' Guide to Rare Die Varieties of United States Coins, Fifth Edition, Volume I) assert that, ""This is an extremely rare variety with fewer than 40 known in any grade.""
