Most people barely glance at the coins jingling in their pockets. But tucked among everyday nickels and pennies, there could be a dime or quarter worth thousands—or even millions. Rare minting errors, unusual metals, and limited production runs have transformed certain dimes and Bicentennial quarters into highly prized collectibles.
In fact, experts estimate that the combined value of these rare coins exceeds $75 million. The best part? Some of these treasures might still be circulating in your spare change, just waiting to be discovered.
Here’s a look at 10 of the rarest and most valuable dimes and Bicentennial quarters you might already own.
1. 1975 No-S Roosevelt Dime
Value: Up to $500,000
Why It’s Rare: Missing the “S” mint mark from the San Francisco Mint
Key Features: No “S” under the date, with a flawless, mirror-like proof finish
Only a few examples of this error dime are known, making it exceptionally rare. Spotting a 1975 Roosevelt dime without the “S” and with a pristine surface could mean you’re holding a coin worth half a million dollars.
2. 1894-S Barber Dime
Value: $1.5 million–$2 million
Why It’s Rare: Only 24 minted; fewer than 10 known today
Key Features: “S” mint mark beneath the wreath on the reverse
One of the most legendary coins in American history, the 1894-S Barber dime rarely appears. While unlikely to be found in everyday circulation, it occasionally surfaces in private sales or hidden estates.
3. 1982 No P Roosevelt Dime
Value: $35,000–$50,000
Why It’s Rare: Philadelphia-minted dime missing the “P” mint mark
Key Features: No mint mark near the date
This rare minting error happened during the transition to marking Philadelphia coins with a “P.” Collectors prize it, and it sometimes shows up in circulated rolls.
4. 1976 Bicentennial Silver Proof Quarter
Value: $10,000+
Why It’s Rare: Limited silver proof mintage
Key Features: “S” mint mark, silver tone instead of standard copper-nickel
Silver proof Bicentennial quarters were made specifically for collectors. If you find one in perfect condition—especially with an error—it could be worth a significant sum.
5. 1976 Bicentennial Quarter Double Die Obverse
Value: $5,000–$25,000+
Why It’s Rare: Noticeable doubling of letters and date on the front
Key Features: Clear doubling on “LIBERTY” and “IN GOD WE TRUST”
Double die coins are highly sought after, and the patriotic Bicentennial design adds to their appeal and value.
6. 1968 No-S Roosevelt Dime
Value: Up to $50,000
Why It’s Rare: Proof coin missing the “S” mint mark
Key Features: No “S” under the date, shiny mirror finish
Struck without the intended mint mark, these rare proof dimes are prized finds for collectors.
7. 1976 Bicentennial Quarter Struck on Wrong Planchet
Value: $15,000–$85,000+
Why It’s Rare: Coin struck on a blank intended for another denomination or foreign coin
Key Features: Odd size, weight, or metal color
This error is a must-have for serious collectors, with coins minted on incorrect blanks being extremely rare.
8. 1942/1 Mercury Dime Overdate
Value: $10,000–$30,000+
Why It’s Rare: The “2” in the date was struck over a “1” due to a die error
Key Features: Overlapping date numbers—look closely!
This famous overdate error can be easy to miss but holds great value when found in good condition.
9. 1976 Bicentennial Quarter with Missing Clad Layer
Value: $2,000–$7,000
Why It’s Rare: One layer of the coin’s metal composition is missing
Key Features: One side appears copper-colored, the other normal
This striking error creates a visually dramatic coin, especially notable on such a historic release.
10. 1996-W Roosevelt Dime
Value: $500–$1,000+
Why It’s Rare: Minted exclusively for special collector sets, never circulated
Key Features: “W” mint mark for West Point
Though not an error, this dime is rare in circulation and often overlooked in mixed collections.
