Authorized in 1863, the Carson City Mint began coinage in 1870 and continued until 1893. It was then operated as a government assay office until 1933 when it was closed as a cost cutting measure. During its operation it made fifty-seven different types of gold coins. It also converted gold bullion and oar into gold bars which were shipped to San Francisco for coinage there. Coins issued from the Carson City Mint used the CC mint mark. Originally established to convert silver from the Comstock Lode to coinage, the Carson City Mint also processed gold in to gold coins.

When first discovered, gold and silver found in Nevada had to be shipped over the Sierra Nevada Mountains to the branch mint in San Francisco. This trip was dangerous and expensive. The Nevada mine owners asked Congress to establish a branch of the mint in their state, and legislation was enacted in 1863. Carson City was chosen as the location for the mint facility because it was near some of the major mining sites.

Between 1870 and 1873, mintage at Carson City was limited because of political reasons. The Mint Superintendent, H.F. Rice was dismissed because of claims that the mint issued some light weight and debased coins. Rice could have been executed. This partly verified information led to frequently seen edge test marks on the gold pieces of this period. Those who wanted the Carson City Mint closed use this discovery to urge the closing. Their real motive was that they wanted the lucrative shipping contracts to move the oar to San Francisco.

The first Carson City coin was the Liberty Seated 1870-CC dollar. A person who had deposited silver at the mint received 2303 silver dollars. Shortly afterwards, gold eagles, half eagles and double eagles were struck. The Carson City Mint did not strike coins made of copper or nickel, and it never struck half dimes, gold dollars, quarter eagles, or three dollar gold coins.
