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.
The U.S. Mint only sells bullion coins, precious metal coins regularly traded on the commodity markets, to authorized purchasers for investment purposes, and the premiums on those coins are low to entice people to invest in gold and silver.
