U.S. Assay Office, 50 Dollars, 1851

As early as 1850, agitation began in Congress for the establishment of a San Francisco branch of the United States Mint. This action was blocked by people from New York — who wanted a branch in their own state — and from Georgia and Louisiana — who argued that any California operation would represent unfair competition to the branch mints in Dahlonega and New Orleans.

The opposition won, and San Francisco would go without a mint for another four years. But it did get an odd sort of hybrid, the United States Assay Office of Gold, striking an odd sort of money — a gigantic, fifty-dollar ingot that would also do duty as a coin. The arrangement was made by the Treasury Department under a contract with Moffat & Company, private assayers and gold coiners in San Francisco.

Augustus Humbert came west to oversee the operation, which got under way at the end of January 1851. For most of the next two years, Humbert’s fifty-dollar "slugs" were the principal accepted currency in California. He was eventually allowed to turn his attentions to the production of smaller, and altogether more useful, coins, ten- and twenty-dollar pieces. And his operation finally laid the framework for a formal, normal branch Mint, which began the production of ordinary federal coinage in the spring of 1854.
