The Greysheet Catalog (GSID) of the U.S. Assay Office - Augustus Humbert (1851–1852) series of Pioneer & Territorial Gold in the U.S. Coins contains 7 distinct entries with CPG® values between $23,000.00 and $6,000,000.00.

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.
