Rare coins continue to intrigue both collectors and investors
While precious metals like gold and silver usually grab the spotlight, certain dimes and quarters—especially rare Bicentennial quarters—have skyrocketed in value due to their rarity, mint errors, and historical meaning. Some of these coins are now worth tens of millions, offering life-changing potential. Let’s uncover 8 exceptional dimes and quarters with a combined value nearing $75 million.
1. 1976 Bicentennial Quarter (No Mint Mark, Double Die) – Worth Over $20 Million
Celebrating America’s 200th birthday, the 1976 Bicentennial Quarter showcases the famous Drummer Boy image. But a rare version without a mint mark and featuring a doubled die on the obverse is worth a fortune.
These coins were mistakenly minted on proof planchets and ended up in circulation. Fewer than 10 are thought to exist. One of them fetched over $20 million at auction. Look out for doubled text in “LIBERTY” and “IN GOD WE TRUST” on any 1976 quarter—you could be holding a multi-million-dollar coin.
2. 1894-S Barber Dime – Valued at $10 Million
Among the scarcest U.S. dimes, the 1894-S Barber Dime was minted in San Francisco with a total of just 24 pieces, and fewer than 10 are known to still exist. These coins were likely given to insiders and VIPs.
One sold for $2 million in 1990, and today’s prices could reach up to $10 million for one in pristine condition. To possess or even see this coin is an incredible experience that very few get to enjoy.
3. 1975 No-S Roosevelt Dime – Worth $2 Million+
This valuable dime is known for a major oversight—it lacks the “S” mint mark that should appear on San Francisco proof coins. Only two of these coins are known to exist.
They were mistakenly included in proof sets and are now among the rarest modern coins. Each is worth more than $2 million. If you own a 1975 proof set, check every dime carefully—it could change your life.
4. 1968-S No-S Roosevelt Dime – Valued Around $500,000
Another elusive error coin, the 1968-S Roosevelt Dime was made as a proof but is missing the “S” mint mark. Though more have surfaced than the 1975 version, they are still incredibly rare.
Fewer than 20 verified coins are known. When in top condition, one of these dimes can sell for as much as $500,000. The missing mint mark and proof finish make it a prized piece in any collection.
5. 1976-S Bicentennial Silver Proof Quarter – Valued at $750,000
This edition of the Bicentennial quarter was made in a silver-clad proof format as part of a special three-coin set. Coins in perfect shape with deep cameo contrast are especially desirable.
A flawless PR70DCAM graded coin has sold for more than $750,000. Many of these quarters are hiding in old proof sets, making them worth a second look if you’re a collector or enthusiast.
6. 1942/1 Mercury Dime – Worth Up to $300,000
A famous overdate error, the 1942/1 Mercury Dime shows a visible “1” beneath the “2” in the date, due to a reused die from the previous year.
Even in lower grades, this coin sells for thousands of dollars. In mint condition, it can go for up to $300,000. This unique error has made the 1942/1 one of the most popular dimes among collectors nationwide.
7. 1982 No P Roosevelt Dime – Valued at $75,000+
A mint mistake in Philadelphia in 1982 caused some Roosevelt dimes to be struck without the “P” mint mark. Thousands entered circulation before the issue was caught.
Though not as rare as other coins on this list, the best-preserved ones can bring over $75,000. Some lucky finders have discovered them in pocket change or even in wrapped bank rolls.
8. 1916-D Mercury Dime – Valued at $250,000+
The 1916-D Mercury Dime was part of the first issue in this series and was struck in small numbers—only 264,000—at the Denver Mint, making it a key date for collectors.
Worn examples can still be worth between $1,000 and $5,000. But those in uncirculated or near-perfect condition can reach beyond $250,000. The small “D” on the reverse confirms its identity.
FAQs
Q1: How do I identify a rare dime or quarter?
Check the coin’s date, condition, and mint mark. Watch for signs like missing letters or doubled images. Use trusted coin reference books or consult grading services such as PCGS or NGC.

Generally, they’re worth face value unless they’re special editions or contain mint errors. High-grade proofs or rare varieties can be worth significantly more.

Yes. Websites like eBay (for certified coins), Stack’s Bowers, or Heritage Auctions are ideal. Always check the buyer’s credibility and consider having your coin graded first.
