1854-FD Octagonal $1. BG-507. Rarity-6+. Liberty Head. AU-55 (PCGS).Light honey-olive patina greets the viewer from both sides of this satiny, appreciably lustrous example. Well defined overall and smooth in hand, it is difficult for us to imagine a more desirable Choice AU for this elusive variety. One of perhaps just 15 to 20 examples of BG-507 known, and sure to see spirited bidding among advanced collectors of California small denomination gold.
