Small in size but rich in history, Mercury dimes remain one of the most collected U.S. coins today. Often mistaken for their namesake, these dimes actually feature Liberty wearing a winged cap, symbolizing freedom of thought—a design that collectors have admired for over a century.
Whether you’ve inherited a handful or stumbled upon one in a coin jar, the question is the same: how much are Mercury dimes worth today? The answer depends on a mix of condition, rarity, silver content, and market demand.
The Mercury dime—officially known as the Winged Liberty Head dime—was minted from 1916 to 1945. Designed by Adolph A. Weinman, it replaced the Barber dime and was eventually succeeded by the Roosevelt design in 1946.
Made of 90% silver and 10% copper, each coin weighs 2.5 grams and contains roughly 0.0723 troy ounces of pure silver. That gives even the most common Mercury dimes a baseline value tied to current silver prices.
Date and Mintmark
Certain years are rarer due to lower mintages, while others have common circulation numbers. Mintmarks—found on the reverse near the bottom left of the fasces—can dramatically impact a coin's value. Coins from the Denver (D), San Francisco (S), and Philadelphia (no mark) mints all carry different levels of desirability.
Condition/Grade
Condition plays a significant role in determining value. Coins in heavily worn condition (Good to Fine) will often be valued at or just above melt, while those in uncirculated condition (Mint State) or with Full Bands (a designation indicating sharp strike detail) can fetch substantially more.
Rarity and Demand
Key dates like the 1916-D and 1942/1 overdate varieties are prized for their scarcity and can be worth hundreds—or even thousands—depending on grade. On the other end, many late 1930s and 1940s issues are more common and carry more modest premiums.
Here’s what collectors can generally expect in the current market:
These values can vary depending on silver prices, collector activity, and coin grading trends. Prices tend to be strongest for coins that have been certified by major grading services like PCGS or NGC.
If you’re holding common-date Mercury dimes in lower grades, they’re often best held as part of a silver stack or sold in bulk. However, if your coin has clear mintmarks, minimal wear, or appears to be from a rare date, it may be worth getting a professional opinion before selling.
Collectors continue to appreciate the Mercury dime for its artistry, historical significance, and manageable size—making it a mainstay in beginner and advanced collections alike.
Mercury dimes may be small, but their impact on American coinage history is significant. In 2025, values remain strong for key dates and high-grade examples, while common coins continue to ride the value of silver. Whether you’re collecting, investing, or simply curious, understanding the market helps you make the most of these classic coins.
