1842-O Liberty Seated Dime. Fortin-107a. Rarity-7. Medium O. MS-65 (PCGS). Retro OGH.This is a beautiful example that ranks among the finest certified survivors of this conditionally challenging issue. The reverse is lightly toned, while the obverse is awash in more vivid and extensive multicolored patina. The strike is suitably bold for a terminal die state example from the Fortin-107 dies, and the surfaces are fully lustrous in a soft satin finish. The 1842-O is the highest mintage Liberty Seated dime from the 1840s with 2,020,000 pieces produced. Attrition through circulation was high, however, and most survivors are well worn. In Mint State this is a rare issue, the present Gem solidly in the Condition Census. Worthy of a strong premium among variety specialists, as well, this coin represents the elusive terminal Fortin-107a attribution, the reverse shattered with myriad cracks and a prominent break filling the top of the letter R in AMERICA.
