Carson City Mint. The Carson City Mint was a branch of the United States Mint in Carson City, Nevada. It primarily minted low numbers of silver coins; however, gold was also minted in greater numbers. The mint was in operation for about 19 years.
Besides the coins now in circulation, there were also half cents, two cent pieces, and three cent pieces. 20 cent pieces were also made for four years, from 1875 to 1878. Bullion and Commemorative Coins are also minted today by the United States Mint.
