The location of the mint mark on a U.S. silver dollar varies depending on the specific type or series of the coin. The placement was changed with different coin designs over the years.
For the Silver Dollar, produced from 1878 to 1904 and again in 1921, the mint mark is located on the reverse (tails) side of the coin. You can find it just below the wreath that encircles the eagle, positioned directly above the letters "D" and "O" in the word "DOLLAR."
On the Peace Silver Dollar, which was minted from 1921 to 1935, the mint mark is also on the reverse side. Its position is below the word "ONE" and to the left of the eagle's tail feathers.
For a more modern example like the Eisenhower Dollar, minted from 1971 to 1978, the mint mark was moved to the obverse (heads) side. It is a small letter located just below the bust of President Eisenhower.
These mint marks identify the U.S. Mint facility where the coin was produced, such as "S" for San Francisco, "D" for Denver, "O" for New Orleans, or "CC" for Carson City. Coins lacking a mint mark were typically struck at the Philadelphia Mint.
