Top Rare Mercury Dimes Value Guide: Mercury Dimes, minted between 1916 and 1945, are among the most beloved silver coins in American numismatics. Officially called the Winged Liberty Head Dime, they earned the nickname “Mercury” because the design resembles the Roman god Mercury. While many examples are common, certain rare dates and mint errors have become incredibly valuable. In 2026, collectors continue to pay big money for the most sought-after Mercury Dimes, making them treasures of both history and investment.
The 1916-D Mercury Dime
The 1916-D is the undisputed king of the series. With a mintage of only 264,000, it is the rarest regular issue Mercury Dime. High-grade examples can sell for tens of thousands, and pristine specimens have crossed into six-figure territory. In 2026, this coin remains the centerpiece of any Mercury Dime collection.
The 1921 Mercury Dime
The 1921 Mercury Dime had a very low mintage due to economic conditions following World War I. Only 1.2 million were struck, making it scarce compared to other years. Collectors prize it for its rarity, and values continue to climb, especially for coins in excellent condition.
The 1921-D Mercury Dime
Even rarer than its Philadelphia counterpart, the 1921-D had a mintage of just over one million. Its scarcity and historical context make it one of the most valuable Mercury Dimes. In 2026, collectors pay premium prices for well-preserved examples, often competing fiercely at auctions.
The 1942/1 Overdate Mercury Dime
This famous error coin was created when a 1941 die was overpunched with a 1942 date. The result is a dramatic overdate visible to the naked eye. Both the Philadelphia and Denver versions exist, and they are among the most sought-after error coins in U.S. history. Values range from thousands to tens of thousands depending on grade, and in 2026, they remain highly desirable.
The 1931-D Mercury Dime
The 1931-D had a low mintage of just over 1.2 million, making it one of the scarcer dates in the series. While not as rare as the 1916-D or 1921 issues, it is still highly collectible. In high grades, it commands strong prices, and in 2026, it continues to be a key coin for serious collectors.
