It’s hard to believe, but a coin that once bought a soda could now be worth more than a luxury home. One such piece is the legendary Mercury Dime, a stunning example of early 20th-century American coinage that’s become a treasure in the world of numismatics. Though it’s no longer found in everyday circulation, a few of these ultra-rare dimes may still be hiding in coin jars, inherited collections, or forgotten drawers.
Let’s uncover everything you need to know about this extraordinary dime—one that recently fetched over $703,000 at auction—and how to identify if you have one in your possession.
🪙 What Is a Mercury Dime?
Minted from 1916 to 1945, the Mercury Dime is officially known as the Winged Liberty Head Dime. It earned the nickname “Mercury” because Lady Liberty’s winged cap closely resembles the Roman god Mercury’s helmet.
Design Details:
- Obverse (front): Lady Liberty wearing a winged cap, symbolizing freedom of thought
- Reverse (back): A fasces (a Roman bundle of rods symbolizing strength through unity) alongside an olive branch for peace
💰 Why One Mercury Dime Sold for $703,000
While most Mercury Dimes are only worth a few dollars due to their silver content, a few rare variations have reached legendary status among collectors. The most valuable of them all?
The 1916-D Mercury Dime
This particular coin is often referred to as the Holy Grail of Mercury Dimes.

- Key Identifier: A small “D” mint mark located to the left of the ‘E’ in ‘ONE’ on the reverse
Estimated Values:
- Circulated condition: $1,000 – $20,000+
