Rare coins have always had a certain magic about them—tiny treasures that can turn ordinary folks into millionaires overnight. While most of us think of gold bars or silver coins when we hear “valuable,” some of the real hidden gems are actually dimes and quarters. Yes, those little coins rattling around in your pocket or jammed in a drawer could be worth a fortune—if you’ve got the right one.
Let’s dive into eight legendary dimes and quarters that together are estimated to be worth around $75 million. Spoiler: You’ll definitely want to double-check your change after reading this.
1. 1976 Bicentennial Quarter (No Mint Mark, Double Die) – Over $20 Million
The 1976 Bicentennial Quarter is famous for its Drummer Boy design, released to mark America’s 200th birthday. But a special version—missing a mint mark and featuring doubled lettering—has become the holy grail of quarters.
These rare errors were struck on proof planchets and somehow ended up in circulation. Fewer than 10 are known to exist. One pristine specimen sold for over $20 million at auction. If you’ve got a 1976 quarter, look closely at “LIBERTY” and “IN GOD WE TRUST” for signs of doubling. You might be holding a piece of American history worth more than a mansion.
2. 1894-S Barber Dime – $10 Million
Only 24 of these dimes were minted in San Francisco, and fewer than 10 remain today. Theories suggest they were gifts for VIPs or internal use only.
One sold for $2 million back in 1990. Today, a top-tier version could fetch $10 million. Seeing one is rare enough—owning one is like holding a slice of American numismatic legend.
3. 1975 No-S Roosevelt Dime – $2 Million+
Here’s a modern mystery: In 1975, two Roosevelt Dimes were accidentally struck without the “S” mint mark normally used on San Francisco proof coins.
They slipped into proof sets and are now worth over $2 million each. If you’ve got a 1975 proof set lying around, it’s time for a close inspection.
4. 1968-S No-S Roosevelt Dime – Around $500,000
Similar to the 1975 dime, this one is also missing the “S” mint mark—another proof coin error. But this time, around 20 examples are known, making it slightly less rare but still incredibly valuable.
Collectors have paid as much as $500,000 for high-grade versions.
5. 1976-S Bicentennial Silver Proof Quarter – $750,000
This quarter was part of a limited silver proof set. The key? It needs to be in perfect PR70 Deep Cameo condition, which is extremely hard to find.
One of these top-graded coins sold for over $750,000. It’s worth checking those old proof sets your grandparents might’ve stored away.
6. 1942/1 Mercury Dime – Up to $300,000
This coin has a visible “1” underneath the “2” in the date—a result of a die being repurposed without fully removing the earlier date.
Even in rough shape, these can bring in a few thousand dollars. In mint condition? Expect up to $300,000. It’s a classic example of how a small minting mistake can create huge value.
7. 1982 No P Roosevelt Dime – $75,000+
A Philadelphia Mint error in 1982 led to thousands of dimes being released without the “P” mint mark—a first in modern U.S. coinage history.
While more common than others on this list, a flawless version can still earn over $75,000. And yes, some folks have found them in circulation.
8. 1916-D Mercury Dime – $250,000+
This was the first year the Mercury Dime was produced, and only 264,000 came out of the Denver Mint. That small “D” on the back makes all the difference.
Lower-grade versions can sell for a few grand, but uncirculated coins have hit over $250,000.

Check the date and mint mark. Look for doubling in the text, missing mint marks, or other unusual features. A coin grading service like NGC or PCGS can confirm authenticity.

Most are only worth face value, but rare variants like silver proofs or error coins can be worth a lot—especially in pristine condition.

Absolutely. Trusted platforms include eBay (for graded coins), Heritage Auctions, and Stack’s Bowers. Always consider getting your coin graded first.
