A United States silver coin produced in 1921 at the San Francisco Mint, it bears a small “S” mark indicating its origin. This identifier differentiates it from coins struck at other mints like Philadelphia (no mint mark) or Denver (“D” mint mark). As an example, a worn coin with the specific mint mark would be less valuable than a pristine one, but might still hold numismatic interest due to its historical context.
The presence of the “S” provides critical information about the coin’s mintage figures, contributing to its rarity and therefore its potential value. This specific mint mark represents a tangible link to the historical operations of the San Francisco Mint, a key institution in the economic history of the American West. Collectors value it for completing sets and understanding the geographic distribution of coin production during that era.
