1855-O Gold Dollar. Type II. Winter-2. EF-45 (PCGS). Pleasing honey-gold patina blankets both sides of this overall boldly defined Choice EF. Faint remnants of original luster persist to further tempt the bidder. As the final New Orleans Mint gold dollar issue and the only one of the brief and challenging Type II design, the 1855-O is a significant and desirable issue in all grades.
