This guide explores the history, rarity, and value of Mercury Dimes, along with tips for collectors and investors.
The History of the Mercury Dime
The Mercury Dime was introduced in 1916 as part of a redesign of U.S. coinage. Designed by Adolph A. Weinman, the coin features Liberty wearing a winged cap, symbolizing freedom of thought. The reverse depicts a fasces, representing strength and unity, along with an olive branch symbolizing peace. Although commonly referred to as the Mercury Dime, the figure is actually Liberty, not the Roman god Mercury. The coin was struck in 90% silver until 1945, when it was replaced by the Roosevelt Dime.
Why Mercury Dimes Are Valuable
Most Mercury Dimes are common, but certain varieties stand out due to rarity, condition, or minting errors. Coins struck in limited quantities, those with unusual features, or examples preserved in pristine condition can command impressive prices.
