Likewise, what is a mint mark on a penny? A mint mark is a letter or other symbol that identifies the mint at which a given coin was made. On most U.S. coins, the mint mark will be a D (for the Denver or Dahlonega mint ), an S (for San Francisco), P was used (for Philadelphia), CC (for Carson City.) or a W (for West Point).
When did the US Mint start putting mint marks on coins?
When the Mint branches in Charlotte, Dahlonega, and New Orleans opened in 1838, mint marks made their first appearance on U.S. coins. Because of its secondary importance in any coin’s design, the mint mark is made as inconspicuous as possible without losing its function.
