Spare Dime: If you’ve ever searched for spare change in your pocket, car, or piggy bank, now is the perfect time to look closely. Some dimes, America’s smallest coin, can be worth a fortune—sometimes even over $1 million!
While rare $2 bills often get the spotlight, dimes hold secrets that could surprise collectors and everyday people alike. Let’s explore the rarest dimes, what makes them so valuable, and how you can figure out if your coins are worth a fortune.
What Makes a Dime Valuable?
Spare Dime: The value of a Spare Dime depends on its age, rarity, mintmark, and condition. Coins from the 19th century or early 20th century are especially valuable. Additionally, silver dimes minted before 1965 contain 90% silver, giving them both historical and material value.
Coins with minting errors, unusual marks, or rare proof editions can also fetch thousands—or even millions—at auction.
The Most Valuable Dime: 1894-S Barber Dime
Spare Dime: The crown jewel of all dimes is the 1894-S Barber Dime. Here’s why it’s so special:
- In 1894, the San Francisco Mint had an accounting shortage of $2.40.
- The mint superintendent minted 24 proof dimes to balance the books, each with the 1894 date and an S mintmark.
- Many of these rare dimes were given to friends and family, including three to his daughter.
Today, only nine 1894-S proof Barber dimes are known to exist. They are extremely valuable, often selling for over $1 million at auctions. In 2016, one such dime fetched $1.9 million!
