U.S. 1865-1889 “Liberty” 3 Cent Nickel. Obsolete for well over a century, this historic coin was introduced after the Civil War, when super-hard nickel was no longer needed for armaments. Only 32 million ever existed. Even in their own day there weren’t nearly enough of these coins to go around. Most got a lot of use in commerce and the great majority were destroyed after recall. The compact piece, with one of the prettiest Liberty engravings on U.S. coinage, was originally referred to as “postage stamp money,” as it was convenient for buying 3 cent stamps. Comparatively few have survived in our well-preserved Fine quality.
