Mercury Dimes are a series of silver dimes produced by the United States Mint from 1916 to 1945, notable for their design featuring Lady Liberty in a winged cap. The 1920 Mercury Dime minted in San Francisco (S mint mark) is particularly collectible due to its lower mintage compared to other years. Coin collectors often seek out these dimes for their historical significance, silver content, and aesthetic appeal. The value of a 1920 San Francisco Mercury Dime can vary significantly based on its condition and market demand.
