1864 Gold Three Dollar
Only 2,630 circulation strike three-dollar gold pieces were produced in 1864, the smallest Philadelphia Mint output up to that point in time. It is thought that just 125 to 175 examples can be accounted for today. A pleasing VF or EF would be a feather in most collectors' caps, and AU coins should be considered rare. The 1864 three is a notable rarity in Choice or finer Mint State grades.
The example to the left was sold by Stack's Bowers Galleries in the August 2017 Denver Auction, where it realized $70,500.
