1851-O Liberty Head Double Eagle. AU-58 (PCGS).;With the largest mintage in this Southern gold series, the 1851-O (315,000 pieces produced) is the most plentiful New Orleans Mint twenty in an absolute sense. However, even in lower About Uncirculated grades the issue is relatively scarce, and Mint State examples are rare. Given the rarity of Mint State survivors, this minimally worn example is sure to be of keen interest to the advanced collector. Very scarce in its own right, both sides exhibit only a trace of highpoint wear to evenly patinated, orange-gold features. The overall strike is bold, and the surfaces appear quite smooth apart from a few minor abrasion. Ample satin luster is discernible as the coin rotates under a light.
