1860-O Liberty Seated Half Dollar. WB-1. Rarity-2. MS-64 (PCGS).This is a warmly and attractively toned example with the most vivid colors evident as the surfaces dip into a light. The strike is sharp to full throughout, and the surfaces are smooth in hand with soft satin luster. With a generous mintage for its era of 1,290,000 pieces, the 1860-O is a popular mintmarked type candidate in the No Motto portion of the Liberty Seated half dollar series. This is a conditionally scarce near-Gem that will appeal to quality conscious collectors.
