The mint mark on a 1928 United States silver dollar, which belongs to the Peace Dollar series, is found on the reverse, or "tails," side of the coin. For a more precise location, one should examine the area just below the word "ONE" in the "ONE DOLLAR" inscription, which is situated above the eagle's tail feathers.
The mint of origin is indicated by a letter, or the absence of one, in this specific spot. A 1928 Peace Dollar with no mint mark was produced at the Philadelphia Mint. If an "S" mint mark is present, the coin was struck at the San Francisco Mint. It is noteworthy that for the year 1928, Peace Dollars were only minted in Philadelphia and San Francisco. Therefore, one would only find either an "S" or no mint mark on a genuine 1928 silver dollar.
