Mount Ophir is a ghost town in Mariposa County, California. It was a mining town founded in 1850 during the California Gold Rush, and was the site of the Mount Ophir Mint, the first authorized mint in California.
Mount Ophir during the early 1850s was a large camp, and stores and tents straggled along the main road for quite a distance. In 1854, Louis Trabucco purchased the stone-walled trading post in Mount Ophir, which was patronized by miners and packers. Its ruins now stand next to the foundation of a large two-store frame hotel built in 1852. The Post Office opened in 1852 under the name "Ophir" but was changed in 1856 to "Mount Ophir" because of the name conflict with Ophir in Placer County.
The gold stamping mill was built in 1850-51 by Moffat and Company, operating under the authority of Augustus Humbert, who had been appointed by President John Tyler to be the federal assayer for the new state of California.

On February 14, 1851 the newspaper, the San Francisco Prices Current, indicated that the production of $50 slugs was about to begin:
The above cut represents the obverse of the United States ingot, or, rather, coin, of the value of $50, about to be issued at the Government Assay Office. It is precisely of this size and shape.... The reverse side bears an impression of rayed work without any inscription. Upon the edges following: 'Augustus Humbert United States Assayer-California Gold 1851.'... The fifty-dollar pieces will be of uniform value, and will be manufactured in the same manner as coins.... By order of the secretary of the Treasury these ingots and coin are to be received for duties and other dues to the United States government, and our bankers, we are advised, will receive them at their stamped value. This will produce an important change in the monetary affairs here, gold dust will immediately go up, … [1]
Much of the coinage produced by the Mount Ophir Mint was later melted down into government ingots. By 1853 the mint was closed. The ruins of the mill are still visible.

California gold coinage is a broad category of privately-issued coin-like items that were used in place of official currency in the United States territory of California during the gold rush of 1849. Since the federal government reserves the right to issue legal tender coins, California gold coinage is a misnomer and actually references coin-like ingots with a stated tender value, tokens with a stated tender value (denominated), and tokens without a stated tender value (non-denominated). These items are only classified as an ingot if the value of the metal was close to the tender value marked on the piece. In spite of the misnomer, it is common practice among numismatists to label coin-like ingots and denominated tokens as 'coins' while labeling the non-denominated tokens as 'tokens'. Also, the small California Gold coins and tokens have been made in many locations other than California, often with a claim of being from California on the piece and these items are generally labeled as California Gold Coins or Tokens.

The New South Wales colonial government concealed the early discoveries, but various factors changed the policy.
