The most important identifying mark on a coins is the Mint Mark. Mint marks are located in different parts of different coins. This mark is important because each mint produces a varying amount or variety of each coin type. The lower the production number, the higher the value of the coin. Coins of a low minting or production number are called Key Dates. Key Date coins have a higher value due to their scarcity. Mints and their marks include “P” for Philadelphia, “D” for Denver and “S” for San Francisco. There was also a Mint in Carson City, Nevada that is now inactive and has been since 1893. Coins minted in Carson City are marked “CC” and are more scarce than coins from any other Mint.
