The Mercury Dime, officially known as the Winged Liberty Head dime, was produced by the United States Mint from 1916 to 1945. The 1939 San Francisco Mercury Dime (S mintmark) is particularly sought after by collectors due to its lower mintage compared to other years. Collectors value the 1939-S for its design by Adolph A. Weinman and its historical significance, as well as its potential to be found in various grades that affect its market value and desirability among numismatists.
