If your coin has a "S" mint mark on it means that it was made at the San Francisco mint in California.
The Philadelphia Mint is in Pennsylvania, the Denver Mint is in Colorado, the San Francisco Mint is in California, and the West Point Mint is in New York.
The New Queensland Mint is located in California, USA.
On a 1962 nickel, the mint mark is located on the reverse side of the coin, to the right of the building depicted in the center. It can either be a "D" for Denver or an "S" for San Francisco, depending on where the coin was minted. If there is no mint mark, it was minted in Philadelphia.
Gold coins are being minted by U.S. Mint HQ in Philadelphia, Pennsylvania. Other mint facilities are located in Denver (Colorado), West Point (New York), San Francisco (California) and Fort Knox (Kentucky).
