The alphanumeric or symbolic inscription designating the facility where a specific coin was produced is a crucial identifier for numismatists. On a particular U.S. dollar coin series minted between 1921 and 1935, this designation indicates where each individual piece originated, such as Philadelphia (often unmarked), Denver (D), or San Francisco (S). For example, a coin with a “D” located on the reverse signifies it was struck at the Denver Mint.
Understanding the location of manufacture is vital due to its influence on a coin’s rarity and, consequently, its potential value. Variations in production volume at different mints resulted in some locations producing far fewer specimens than others. Additionally, the presence or absence of a location indicator, as well as its specific characteristics, can significantly impact collector interest, making it a key factor in determining the desirability and worth of a piece.
