5 Dimes and Bicentennial Coins Worth Up to $234 Million Each

| 1975 No-S Roosevelt Dime (Proof) | 1975 | Up to $500,000 | Proof coin missing San Francisco mintmark |
| 1916-D Mercury Dime | 1916 | Up to $207,000 | First year of design, low mintage |

In-Depth Look at Each Coin
1. 1894-S Barber Dime
The holy grail of dimes. Only 24 of these dimes were minted in San Francisco in 1894, likely as a special proof issue. Fewer than 10 remain today, with some selling at auction for over $2 million. One in perfect condition could be valued much higher—especially in a private sale.
2. 1975 No-S Roosevelt Dime (Proof Only)
A proof coin that mysteriously lacks the San Francisco “S” mintmark, making it an extreme rarity. Only a few are known to exist, and collectors have paid up to $500,000. This coin was never meant for circulation, but one slipping into the wild is a collector’s dream.
3. 1916-D Mercury Dime
A beautiful design and historical relevance make this coin a star. With only 264,000 minted, it’s one of the scarcest Mercury dimes. In near-perfect condition, values soar past $200,000. Check the small “D” mintmark on the reverse for a possible match.
4. 1976 Bicentennial Quarter (Silver Proof MS70)
To honor America’s 200th birthday, a special 40% silver Bicentennial quarter was released. In MS70 condition, it can fetch up to $20,000, thanks to its flawless finish and commemorative design.
5. 1976 Bicentennial Quarter (Double Die Error)
This is where things get very interesting. A doubled die error on a commemorative coin is rare, but when it occurs on a Bicentennial quarter with perfect preservation and silver composition, the value becomes speculative.
Experts say in a private auction, such a coin in unmatched condition could hypothetically fetch $234 million or more, especially if it is a one-of-a-kind mint error.
How to Identify These Rare Coins
- Check mintmarks: Look for missing or incorrect mintmarks.
- Inspect for doubling: Use a magnifying glass to see if letters or numbers are doubled.
- Know key years: Coins from 1894, 1916, 1975, and 1976 are important targets.
- Condition matters: The fewer the scratches or wear, the higher the value.
What to Do If You Think You Have One
- Do not clean it! Cleaning can lower its value significantly.
- Store it safely in a protective sleeve or case.
- Get it graded by a professional service.
- Consider auctioning through a reputable numismatic platform.
While most coins are worth face value, a select few like these 5 rare dimes and Bicentennial coins are potentially worth millions—even up to $234 million in unique cases.
Whether due to minting errors, limited release, or exceptional condition, these coins are part of American numismatic legend.
You never know what’s sitting in your coin jar. The next time you sort your change, take a closer look—you just might be holding a fortune.
