Liberty Double Eagles
1851-O $20 -- Altered Surfaces -- PCGS Genuine. Unc Details. Variety 1. The 1851-O Liberty double eagle claims the highest mintage of the O-mint series, at 315,000 pieces, making it a favorite choice of branch mint type collectors. This still-attractive specimen displays sharply detailed design elements, with some unobtrusive graffiti on Liberty's neck, near the truncation. The lustrous orange-gold surfaces are unworn and lightly marked, aside from the noted flaws.
