1860-O Liberty Seated Dime. Fortin-101, the only known dies. Rarity-6-. EF Details--Environmental Damage (PCGS). The first of only two New Orleans Mint dimes of the Liberty Seated, Legend Obverse type, the 1860-O is far rarer than the 1891-O in all grades and is actually a key date in this series. The mintage was just 40,000 pieces and survivors are elusive in all grades. The typical example grades no finer than VF, and many are impaired from having been buried; the present coin is perhaps a ground find. Still, it is an above average 1860-O dime in terms of remaining detail, and it is sure to see spirited bidding among Liberty Seated specialists and New Orleans Mint enthusiasts.
