Most Valuable Mercury Dimes: The Mercury Dime, officially known as the Winged Liberty Head Dime, is one of the most celebrated silver coins in American numismatics. Struck from 1916 to 1945, this small yet intricately designed coin has captured the attention of collectors for over a century. In 2026, interest remains strong, particularly for the 1916‑D and other rare varieties, as both historical significance and silver content continue to support their value.
The Mercury Dime is not only admired for its artistry by Adolph A. Weinman but also for its investment potential. From common circulated coins to high grade registry examples, the series offers a wide spectrum of opportunities for collectors of all levels. This guide explores the most valuable Mercury Dimes, key dates, rare varieties, grading, and market trends in 2026.
The History of the Mercury Dime
The Mercury Dime replaced the Barber Dime in 1916. Its obverse design features Liberty wearing a winged cap, symbolizing freedom of thought, while the reverse shows a fasces tied with an olive branch, representing strength and peace. The public quickly nicknamed the coin the Mercury Dime due to the winged cap’s resemblance to the Roman god Mercury.
All Mercury Dimes were minted in 90 percent silver, giving them intrinsic value beyond their nominal ten cents. The coin remained in production until 1945, when the Roosevelt Dime replaced it, commemorating the late president. Despite being replaced, the Mercury Dime remains a cornerstone of American coin collecting.
Mercury Dime Silver Content and Intrinsic Value
Every Mercury Dime contains 90 percent silver and 10 percent copper, weighing 2.5 grams, or 0.0723 troy ounces of pure silver.
Because of this silver content, even heavily circulated coins carry a melt value. In 2026, with silver prices remaining strong, Mercury Dimes have a reliable baseline value, making them appealing to both collectors and silver investors.
Coins in higher grades or with rare mint marks often command premiums far exceeding melt value, which is why rarity and condition are critical for valuation.
Most Valuable Mercury Dime: The 1916‑D
The 1916‑D Mercury Dime is widely considered the king of the series. Struck at the Denver Mint, only 264,000 were produced, making it the lowest mintage regular issue Mercury Dime. The combination of rarity and collector demand has made it the most sought-after date in the series.
High grade examples of the 1916‑D have sold for hundreds of thousands of dollars at auction. In 2026, a well-preserved MS65 or higher coin can still command prices exceeding $15,000, with exceptional specimens breaking records.
The 1916‑D exemplifies the interplay of scarcity, historical importance, and condition rarity that defines Mercury Dime collecting.

Beyond the 1916‑D, several Mercury Dimes are considered highly valuable:
1916‑S
Produced at the San Francisco Mint with 48,000,000 coins, many circulated heavily, but top grade specimens remain valuable.
