Imagine buying a small box of old coins at a garage sale, only to discover that one of them is worth millions of dollars. This might sound like a dream, but it has happened to lucky collectors who unknowingly stumbled upon rare dimes hiding in plain sight. In 2025, rare coin prices are breaking records, and some dimes have reached seven-figure valuations. Let’s take a look at three dimes that have turned ordinary people into millionaires.
1. 1894-S Barber Dime – Worth Over $2 Million
The 1894-S Barber Dime is one of the rarest and most valuable dimes ever minted, with only 24 pieces originally struck and fewer than 10 known to exist today. One lucky collector found this dime at a garage sale inside a box of mixed coins and later sold it for over $2 million at auction. If you ever come across a dime from 1894 with an “S” mintmark, you might be holding a life-changing fortune.
2. 1916-D Mercury Dime – Sold for $1 Million
Another incredible find was a 1916-D Mercury Dime, the key date of the Mercury dime series. With only 264,000 minted, it is highly sought after by collectors. A man in Colorado unknowingly purchased one at a yard sale for just a few dollars and later discovered it was in mint condition. It was professionally graded and sold at auction for nearly $1 million.
3. 1975 No-S Roosevelt Dime – Auctioned for $500,000+
This ultra-rare dime was mistakenly minted without the “S” mintmark, making it one of the most valuable modern dimes. A woman found this coin in a jar of loose change at a flea market and later had it authenticated. Since only two examples are known to exist, the coin fetched over $500,000 at auction. If you ever spot a 1975 Roosevelt dime missing its mintmark, it could be worth a small fortune.
Stories like these prove that hidden treasures can be found in unexpected places. Garage sales, flea markets, and even old coin jars can hold rare and valuable dimes worth thousands—or even millions—of dollars. If you come across old coins, be sure to inspect them carefully, check their mintmarks, and research their history. You never know—you might be sitting on a million-dollar dime without realizing it!
