The 1921-D 10C Mercury Silver Dime was minted in Philadelphia. The US mint selected Adolph A. Weinman’s design from among submissions by several leading US sculptors of the era. Although no one will ever know for sure, the Liberty model on the coin face is thought to be Elsie Stevens, poet Wallace Stevens’ wife. The coin head features the goddess Libertas (liberty), wearing a winged Phrygian cap. Weinman intended for the Liberty head to symbolize “liberty of thought.” The Liberty head’s tight curls and the Liberty Cap feathers, are crafted in careful relief. These silver dimes were originally referred to as Liberty Head dimes for the goddess Liberty, but many people in the press confused the image with the Greek God Mercury, immediately after the coin was released. “Mercury” dime is therefore a misnomer, but it has stuck. The reverse side of the 1921-D 10C Mercury Dime features a fasces, a bound bundle of wooden rods with an axe blade emerging, symbolizing unity, surrounded by an olive branch. Weinman wrote that unity symbolizes a nation’s strength, which is why he included the fasces on the dime. Fasces also symbolize justice and war. Although many mercury dimes were minted between 1916 and 1945, silver dimes from the years between 1920 and 1923 can be rarer. The post war recession between 1920 and 1923 limited the number of coins minted during these years, which can make them rarer too. Collectors and speculators can value mercury dimes from these years, due to their limited mintage. The dime composition is silver with a fineness of 0.900. If you look carefully at the numerals on the silver coin, you can see the unique numeral styles. In the year “1921,” the numerals 1 are bowed inward at their centers and have broad bases. The numeral 9 also has a unique design, with a deco style open loop. You can see the designer’s initials “AW” midway between the date and the letter Y in “LIBERTY” on the coin face. The mintmark is on the dime reverse, appearing to the right of the first E in “one dime.” The Silver Mercury dime can be an important piece of coin history. The Mercury Dime can be so appreciated by coin enthusiasts and mint professionals that it was re-struck in gold for its centenary in 2016. The gold edition sold out within 45 minutes. The coin series continued until Franklin Roosevelt’s death in 1945 as the lionized president was immediately featured on US currency. The dime was chosen because of Roosevelt’s association with the March of Dimes. The 1921-D 10C Mercury Silver Dime can be a wonderful addition to any serious coin collection and an investment highly rated by the NGC.
