1853 $1 BG-604 Eagle N1 Certification #25614357, PCGS #10520
The 1853 BG-604 Gold Dollar is one of the most desirable of all the California Fractional Gold pieces. It is certainly, the most valuable. Jay Roe paid a reported $100,000 for the best of only two known examples. When Roe's collection was sold in 2003, the coin realized $80,500. In 2005, the coin resold for $82,800, and it would probably be worth over $100,000 again today.
The obverse of this variety features a Liberty Head facing left; the initial's "G.G." beneath the bust stand for Gaime, Guillemot & Co., for whom the coin was made by Frontier, Deviercy & Co. The unique reverse of this variety has an unusual, fatty eagle with a crest atop its head resembling that of a cockatoo. This is the only round Dollar with an eagle on the reverse.
The only other example known to exist shows the details of an About Uncirculated coin, but it has a small patch of heavy scratches in the left obverse field opposite Liberty's eye. That coin, which had been off the market since 1956, reappeared in the January 2016 Heritage auction.
