Based on general numismatic knowledge, as the provided context is not relevant to the question, the mint mark on a 1923 Peace silver dollar is located on the reverse, or "tails," side of the coin.
To find it, you should examine the area just below the word "ONE" in the "ONE DOLLAR" inscription. The mint mark will be positioned slightly to the left of the eagle's tail feathers. For the year 1923, there are two possible mint marks: a "D" for coins struck at the Denver Mint and an "S" for those from the San Francisco Mint.
It is critical to note that if there is no mint mark present in this location, the coin was minted in Philadelphia. During this period of US coinage, the Philadelphia Mint did not place a "P" mint mark on its silver dollars. Therefore, the absence of a letter signifies its origin as Philadelphia.
