The Greysheet Catalog (GSID) of the Dunbar & Company (1851) series of Private & Pioneer Gold in the U.S. Coins contains 1 distinct entries with CPG® values between $400,000.00 and $750,000.00.
Augustus Humbert, a New York watchcase maker, was appointed United States assayer,
and he placed his name and the government stamp on the ingots of gold issued by Moffat & Co. The assay office, a provisional government mint, was a temporary expedient to
accommodate the Californians until the establishment of a permanent branch mint.
The fifty-dollar gold piece was accepted by most banks and merchants as legal
tender on a par with standard U.S. gold coins and was known variously as a slug,
quintuple eagle, or five-eagle piece. It was officially termed an ingot.
