Mercury Dimes, officially known as Winged Liberty Head dimes, were minted in the United States from 1916 to 1945. The 1928 Mercury Dime minted in San Francisco (S mint mark) is particularly sought after by collectors due to its lower mintage. This coin features a depiction of Liberty wearing a winged cap on the obverse and a fasces with an olive branch on the reverse. The 1928-S is valuable in higher grades due to its scarcity and popularity among numismatists.
