Rare Mercury Dime Worth $21.31 Million is Still in Circulation

The Mercury dime is one of the most beloved coins in American numismatics. Minted from 1916 to 1945, its striking design and historical relevance make it a must-have for collectors. While most Mercury dimes are relatively affordable, a handful of rare examples—like the 1916-D—have fetched staggering prices, with top-condition specimens worth over $21 million. Whether you’re an investor, a history buff, or simply curious, understanding what makes these dimes valuable can uncover both a fascinating story and a potential fortune.

What Is the Mercury Dime?

The Mercury dime, officially known as the Winged Liberty Head dime, was introduced in 1916 and struck until 1945. Its obverse features a portrait of Liberty donning a winged cap, often mistaken for the Roman god Mercury—hence the nickname. The reverse displays a fasces, symbolizing strength and unity, alongside an olive branch representing peace.

These dimes were composed of 90% silver and 10% copper, giving them not just historical but also intrinsic value. Each coin weighs 2.5 grams and measures 17.9 mm in diameter.

Key Factors That Affect Value

Several variables influence the value of a Mercury dime. The most critical are:

• Mint Year and Mark: Rare years and limited mintages are worth significantly more.
• Condition (Grade): Coins graded “Mint State” (MS) command premium prices.
• Rarity: Some dimes were minted in extremely low quantities, boosting their value.
• Demand: A strong collector base drives prices higher for sought-after issues.
• Provenance: Coins with documented histories or from notable collections can sell for more.
