Most people toss spare change into jars without a second thought. But what if one of those overlooked coins could be worth thousands—or even millions—of dollars? Across the U.S., rare dimes and nickels from earlier decades are still quietly circulating, hiding in plain sight. These coins may look ordinary, but they carry incredible value for collectors—and could even help you pay off debt or fund a major expense.
Why Are Rare Coins Still in Circulation?
Over time, many rare coins have ended up back in circulation due to estate clear-outs, inherited coin jars, or simply being spent unknowingly. Most people don’t realize they’re holding a small fortune in their hands. That’s why regularly checking your pocket change, coin rolls, or old collections can sometimes lead to a life-changing discovery.
Here Are 7 Rare Dimes and Nickels You Might Still Find
1. 1916-D Mercury Dime
Estimated Value: Up to $15,000+
The 1916-D Mercury Dime is one of the most sought-after dimes in American numismatic history. Minted in Denver, only 264,000 of these coins were produced. The small “D” mint mark on the reverse is your clue. If you spot one in decent condition, you could be holding a five-figure payday.
2. 1942/1 Mercury Dime Overdate
Estimated Value: Up to $10,000+
This fascinating error coin features a “2” printed over a “1” in the date. Produced during World War II by both the Philadelphia and Denver mints, it’s subtle enough to go unnoticed in regular circulation. But collectors will pay thousands for one in good shape.
3. 1970-S Proof Roosevelt Dime (No “S” Mint Mark)
Estimated Value: Around $500,000 (Proof Condition)
This modern rarity is a 1970-S proof dime that escaped the San Francisco Mint without its “S” mint mark. Intended for proof sets only, a few of these coins may have entered general circulation by accident. If you spot one, you’re looking at a half-million-dollar find.
4. 1913 Liberty Head Nickel
Estimated Value: Over $4 Million
Only five examples of the 1913 Liberty Head Nickel are known to exist. While extremely rare and unlikely to be found in circulation, stories persist of coins turning up in dusty drawers and family collections. If you ever encounter one, contact a numismatic expert immediately.
5. 1943-P Jefferson Nickel (3 Over 2 Overdate)
Estimated Value: Up to $10,000
This wartime nickel features a unique overdate error, where the number “2” appears faintly under the “3” in the year. With the U.S. Mint switching to a silver-nickel alloy during WWII, error coins like these slipped through and may still be out there.
6. 1950-D Jefferson Nickel
Estimated Value: Up to $1,500+
The 1950-D Jefferson Nickel had the lowest mintage of any coin in the series—just 2.6 million made. Because it wasn’t recognized as special at the time, many ended up being spent. Today, collectors actively search for well-preserved examples.
7. 1964 SMS Jefferson Nickel
Estimated Value: $8,000 to $32,000+
SMS stands for “Special Mint Set,” and the 1964 SMS Jefferson Nickel is a coin shrouded in mystery. These coins were likely part of a test batch and never officially released. They feature a unique matte finish and razor-sharp details—if you find one, you’re looking at a rare and valuable coin.

A single rare find could be hiding in your everyday transactions. Make it a habit to check your change—especially older nickels and dimes.
