The identifying symbol indicating where a coin was produced, as found on examples of the 1922 silver Peace dollar, provides key information about its origin and potential value. These symbols, typically letters, distinguish coins struck at different United States Mint facilities. For instance, the absence of a mark signifies Philadelphia production, while a “D” indicates Denver, and an “S” denotes San Francisco.
Knowing the source of these dollars is essential for collectors because mintage figures varied significantly between mints. This variation directly impacts rarity and, consequently, the desirability and market price. Certain mint marks, particularly those associated with lower production numbers or specific historical circumstances, contribute to increased premium for these pieces.
