A small letter or symbol indicating the U.S. Mint branch where a coin was produced can be found on the surface of the 1921 silver dollar. These marks, typically located on the reverse side of the coin near the eagle, denote the specific facility responsible for striking the piece. For example, the absence of a mark signifies production at the Philadelphia Mint.
The presence or absence of a particular symbol, and even its specific size or style, can significantly influence the value and collectibility of these coins. Coins from certain mints, particularly those with lower production numbers, are often more sought after by numismatists. Studying these identifiers provides key insights into the coin’s origin, rarity, and historical context within the broader landscape of early 20th-century American coinage.
