The location of the mint mark on a U.S. silver dollar varies depending on the specific series of the coin. For the two most common classic silver dollars, the and the Peace dollar, the mint mark is found on the reverse side.
On a Morgan Silver Dollar, which was minted from 1878 to 1904 and again in 1921, you can find the mint mark on the reverse, or "tails," side of the coin. It is a small letter located beneath the wreath that encircles the eagle, positioned just above the letters "D" and "O" in the word "DOLLAR". Common mint marks include "S" for San Francisco, "O" for New Orleans, "CC" for Carson City, and "D" for Denver. If no mint mark is present, the coin was struck at the Philadelphia Mint.
For the Peace Silver Dollar, minted from 1921 to 1935, the mint mark is also on the reverse. You can find it below the word "ONE" and to the lower left of the eagle's tail feathers. The mint marks for Peace dollars include "S" for San Francisco and "D" for Denver. Similar to the Morgan dollar, a Peace dollar without a mint mark indicates it was produced at the Philadelphia Mint.
