1854-FD Octagonal $1. BG-506. Rarity-7. Liberty Head. AU-53 (PCGS). A particularly impressive example of yet another rarity from the Oregon Collection. Warmly patinated in deep honey-orange, both sides are boldly defined with plenty of satiny luster remaining. The Bob Leonard census, published in the 2003 edition of the Breen-Gillio reference <em>California Pioneer Fractional Gold</em>, lists just 10 examples of this elusive variety, again with the qualifier "Probably some duplication." <em>PCGS CoinFacts</em> asserts that the actual extant population may be as few as six pieces. Perhaps not surprisingly, market appearances for BG-506 are few and far between, and this PCGS AU-53 is one of the nicest to be offered at auction in recent decades. From the Oregon Collection.
