Mercury Dimes, officially known as Winged Liberty Head Dimes, were minted in the United States from 1916 to 1945. The 1939 Mercury Dime, produced at the San Francisco Mint, features a prominent depiction of Lady Liberty on the obverse and a fasces on the reverse. Collectors value this coin for its historical significance, artistic design, and varying mint marks, with the San Francisco version being particularly sought after due to lower mintage numbers compared to other years. The 10 cent denomination reflects its practical use during its circulation period.
