Where is the mint mark on a 1941us half dollar?

On a 1941 U.S. half dollar, the mint mark is located on the reverse side of the coin, just below the eagle's tail feathers. It will be positioned to the left or right of the ribbon that holds the olive branches. Depending on the mint where the coin was produced, the mint mark can be either a "D" for Denver, an "S" for San Francisco, or no mark at all for the Philadelphia mint.
