Behold this 1852 Augustus Humbert gold $50 piece

Kagin’s held its West Coast Auction on Sept. 15 in conjunction with the Santa Clara Coin Expo in California, and as expected, privately issued pioneer and territorial gold coins stole the show. As the firm’s president Don Kagin wrote in the introduction, the convention is “by far the largest coin show in northern California,” concluding, “so it is fitting that this sale features some of the most iconic and fascinating coins and related material associated with the great California Gold Rush.”

One of those fascinating coins is featured here:
