For coin enthusiasts, discovering a rare dime or quarter is like unearthing buried treasure. While most coins in circulation are ordinary, a handful of unique issues—mistakes, low-mintage releases, or historically significant pieces—can be worth thousands (or even millions!). Let’s dive into five dimes and one legendary quarter that could turn your pocket change into a windfall.
1. 1946-S Roosevelt Dime
History & Significance
The Roosevelt Dime debuted in 1946 to honor President Franklin D. Roosevelt and his March of Dimes campaign to combat polio. The San Francisco Mint (marked by a tiny “S”) produced far fewer dimes this year compared to Philadelphia and Denver.
Why It’s Valuable
- Scarcity: Only 27 million were minted in San Francisco.
- Condition Rarity: Few survived in uncirculated condition.
- Full Bands: Specimens with crisp details on the torch’s bands command the highest prices.
Potential Value
- Circulated: $50–$500
- Uncirculated (Full Bands): Up to $25,000+
2. 1968-S “No-S” Proof Roosevelt Dime
The Mint’s Costly Mistake
This proof dime was struck in San Francisco but accidentally omitted the “S” mintmark. Only a handful exist.
Why It’s Valuable
- Extreme Rarity: Fewer than 10 confirmed specimens.
- Proof Quality: Mirror-like finish adds to its appeal.
Potential Value
- $20,000–$30,000+ at auction.
3. 1975 No-S Proof Roosevelt Dime
A Modern Rarity
Proof coins are specially made for collectors, but a few 1975 dimes escaped the San Francisco Mint without their “S” mintmark.
Why It’s Valuable
- Survival Count: Only 2–3 examples known.
- Historical Error: One of the rarest modern U.S. coins.
Potential Value
- $500,000+ (auction record in 2019).
4. 1916-D Mercury Dime
The Iconic Winged Liberty
The Mercury Dime (featuring Lady Liberty in a winged cap) is a numismatic favorite. The 1916-D issue, struck in Denver, is legendary for its scarcity.
Why It’s Valuable
- Low Mintage: Just 264,000 produced.
- High Demand: Beloved design + rarity = collector frenzy.
Potential Value
- Worn: $1,000+
- Mint State: $100,000–$250,000
5. 1894-S Barber Dime
The Million-Dollar Mystery
Only 24 Barber Dimes were struck at the San Francisco Mint in 1894. Theories suggest they were made as gifts or test strikes.
Why It’s Valuable
- Ultra-Rarity: Only 9 confirmed survivors.
- Mystery: No clear historical documentation of their purpose.
Potential Value
- $2 million+ (last auction sale in 2016).
6. 1976 Bicentennial Quarter
America’s 200th Anniversary Star
Celebrating the U.S. bicentennial, this quarter features a colonial drummer on the reverse. Most are common, but specific varieties are goldmines.
Why It’s Valuable
- Silver Composition: 40% silver proofs (stamped “S”) are worth $10–$25.
- Errors: Double strikes, missing mintmarks, or off-center designs.
Potential Value
- Error Coins: $500–$45,000+
(A unique doubled die obverse sold for $44,063 in 2023!)

FAQs
1. How do I know if my Bicentennial Quarter is rare?
Look for silver proofs (stamped “S”), missing mintmarks, or dramatic errors like double strikes.
2. Where can I get my coin appraised?
Visit certified numismatists, auction houses (e.g., Heritage Auctions), or use online tools like PCGS or NGC.
3. Are rare dimes still found in circulation?
Yes! Older dimes like the 1968-S “No-S” or 1946-S occasionally surface in coin rolls or hand-me-down collections.
4. What’s the rarest coin on this list?
The 1894-S Barber Dime, with only 9 known survivors, is the “holy grail.”
5. Can I clean my coins to increase value?
Never clean coins! Harsh cleaning reduces their value by damaging surfaces.
Final Thought
Every coin tells a story—and some stories pay off big. Whether it’s a Depression-era dime or a bicentennial quarter, take a closer look at your spare change. You might just hold history (and a small fortune) in your hands!
