That jar of loose change sitting on your dresser might contain more than just laundry money. While most modern coins remain worth exactly their face value, certain rare dimes and Bicentennial coins can be worth hundreds, thousands, or even millions of dollars to collectors.
The stories behind these valuable coins—how they were made, why they’re rare, and what makes them special—add fascinating dimensions to their considerable monetary worth.
This exploration reveals six extraordinarily valuable dimes and several surprising Bicentennial quarters that command significant premiums in today’s collector market.
From genuine rarities worth millions to overlooked varieties potentially hiding in pocket change, these coins represent the fascinating intersection of history, minting errors, and collector enthusiasm that drives the numismatic marketplace.
The Million-Dollar Dimes: Tiny Treasures with Massive Value
Among America’s smallest denomination coins, dimes have produced some of the most valuable rarities in U.S. numismatic history.
1. The 1894-S Barber Dime: The Holy Grail of Dimes
The 1894-S Barber dime stands as one of the most legendary coins in American numismatics. With only 24 examples struck at the San Francisco Mint and a mere 9 confirmed survivors known today, this dime represents the pinnacle of rarity.
The story behind its creation adds another layer of mystique. San Francisco Mint Superintendent John Daggett reportedly ordered these dimes struck to balance the mint’s books by an odd $2.40.
He allegedly gave three to his daughter Hallie, telling her to save them as they would be valuable someday. According to numismatic lore, she spent one on ice cream on a hot summer day, creating the famous “Ice Cream Specimen” that became one of the most sought-after coins in existence.
In recent years, these dimes have commanded extraordinary prices:
- In 2016, an example graded PCGS Proof-66 sold for $1,997,500 at auction
- In 2019, another specimen brought $1,320,000 despite showing evidence of circulation
- Private transactions have reportedly reached even higher figures for the finest preserved examples
The extreme rarity, fascinating backstory, and exceptional quality of surviving specimens combine to make the 1894-S one of the most valuable coins in American numismatics.
2. The 1916-D Mercury Dime: Denver’s Silver Masterpiece
While not reaching the seven-figure values of the 1894-S, the 1916-D Mercury dime represents the key date in one of America’s most beloved coin series.
Only 264,000 were struck—a tiny number compared to the millions produced at other mints that year—creating an instant rarity when the Mercury dime series debuted.
The Denver Mint prioritized quarter production over dimes in late 1916, resulting in this unexpectedly low mintage.
By the time collectors began assembling complete sets of the new design, many examples had already circulated heavily or been lost, making high-grade specimens particularly elusive.
Today, values vary dramatically based on condition:
- Well-worn examples: $1,000-$3,000
- Mid-grade circulated specimens: $5,000-$10,000
- Uncirculated examples: $10,000-$30,000
- Gem specimens with “Full Bands” (complete horizontal bands on the fasces): $50,000-$150,000
In 2018, a perfect MS68 Full Bands example sold for $207,000, showing the premium the market places on exceptional preservation.
Despite their value, these coins occasionally turn up in old collections where owners remain unaware of their significance.
3. The 1942/1 Mercury Dime: Wartime Overdate Error
One of the most dramatic die errors in American coinage occurred during the resource constraints of World War II. To save materials and labor, the Mint reused a 1941-dated die, attempting to re-engrave it as 1942. The result: clear remnants of the “1” remain visible beneath the “2” in the date.
Two varieties exist—one from Philadelphia (no mintmark) and an even rarer Denver version (with D mintmark). The Philadelphia version typically brings:
- $500-$1,500 in circulated grades
- $2,500-$7,500 in lower mint state
- $10,000-$30,000 for gem examples
The scarcer Denver counterpart commands approximately three times these values. What makes this error particularly appealing to collectors is its visibility—the overdate can be seen without magnification, making it accessible to novice collectors who might discover one in circulation.
4. The 1968 No-S Proof Roosevelt Dime: Modern Mint Mystery
In 1968, a small number of proof Roosevelt dimes were struck without the expected “S” mintmark from the San Francisco facility. While exact production figures remain unknown, numismatic researchers estimate fewer than 30 authentic examples exist, making this a significant modern rarity.
These coins were distributed only in government proof sets, creating a sensation when collectors discovered the error. Today, authentic examples command $10,000-$20,000 at auction.
Similar “No S” proof dimes were produced in 1970, 1975, and 1983, each representing significant collecting opportunities.
Despite their substantial value, these coins occasionally remain undiscovered in original government proof sets, representing potential windfalls for collectors who examine their holdings carefully.
Bicentennial Coins: America’s Birthday Money
The Bicentennial coinage program of 1975-1976 produced quarters, half dollars, and dollars bearing the dual date “1776-1976” to commemorate America’s 200th birthday. While most remain worth only face value, several varieties command substantial premiums from collectors.
5. The 1976 No-S Proof Bicentennial Quarter: America’s Valuable Birthday Mistake
By far the most valuable Bicentennial coin is the legendary “No S” proof quarter. Proof coins are specially made collector versions struck with polished dies and planchets, featuring mirror-like fields and frosted designs.
All proof coins struck at the San Francisco Mint should bear the “S” mintmark, but in a rare error, a small number of Bicentennial quarter proof dies were created without the crucial “S” mintmark.
The absence of the mintmark created a major numismatic rarity:
- Only about 10-15 examples are known to exist
- Recent auction prices range from $40,000 to $55,000
- A particularly pristine example graded PR68 sold for $52,875 in 2020
All known examples emerged from proof sets sold directly by the U.S. Mint, meaning this variety never entered circulation.
The fact that such valuable coins could come from regular government offerings that originally sold for just a few dollars adds to their allure.
6. The 1976 Doubled Die Bicentennial Quarter: Hidden Variety
Several doubled die varieties exist among Bicentennial quarters, with the most prominent showing doubling on the obverse (front) design, particularly visible in the lettering of “LIBERTY” and the date. While not approaching the value of the “No S” proof variety, these doubled dies still command respectable premiums:
- $25-$100 for circulated examples
- $100-$300 for uncirculated specimens
- $500+ for gems with minimal marks
Because they entered regular circulation, these varieties might still be discovered in pocket change or coin rolls by sharp-eyed collectors.
The doubling typically appears most prominently on the letters “LIBER” in LIBERTY and in the date digits.
Beyond the Top Six: Other Valuable Varieties to Watch For
While not reaching the values of our top six, several other dimes and Bicentennial coins command significant premiums worth noting.
Additional Valuable Dimes
- 1796 Draped Bust Dime: America’s first dime, worth $2,000-$200,000 depending on condition
- 1874-CC Liberty Seated Dime: Key Carson City issue, worth $1,000-$50,000
- 1921 and 1921-D Mercury Dimes: Semi-key dates worth $50-$10,000 depending on condition
- 1982 No-P Roosevelt Dime: Missing Philadelphia mintmark error, worth $50-$300
More Bicentennial Varieties
- 40% Silver Varieties: Special collector versions in 40% silver composition, worth $5-$25
- Bicentennial Quarter Errors: Off-center strikes ($25-$200), wrong planchet errors ($200-$500), and double strikes ($100-$300)
- Prooflike Business Strikes: Occasionally, regular circulation coins exhibit mirror-like surfaces similar to proofs, commanding $10-$50 premiums
How to Search for These Valuable Coins
For those inspired to hunt for these numismatic treasures, several approaches prove most effective.
Examining Circulation Finds
When reviewing pocket change or coin rolls:
- Check dates carefully on all dimes, watching for key dates like 1916-D
- Examine the “2” in 1942 dimes for signs of an underlying “1”
- Look for doubled lettering on Bicentennial quarters, particularly in “LIBERTY”
- Weigh suspicious Bicentennial quarters (silver versions weigh more than copper-nickel)
A 5x to 10x magnifying glass or loupe helps identify subtle varieties and errors that might otherwise go unnoticed.
Searching Proof and Mint Sets
For those with access to original government-issued coin sets:
- Examine 1968, 1970, 1975, and 1983 proof sets for dimes missing the “S” mintmark
- Check 1976 proof sets for Bicentennial quarters without the “S” mintmark
- Look for unusual toning, striking errors, or varieties within uncirculated sets
Original government packaging preserved coins from environmental damage, making these sets potential sources for high-grade examples.
Bank Roll Hunting
A more systematic approach involves searching through rolls of coins obtained from banks:
- Dime rolls contain 50 coins ($5 face value)
- Quarter rolls contain 40 coins ($10 face value)
- Customer-wrapped rolls often prove more productive than machine-wrapped rolls
- Rural banks sometimes provide better hunting grounds as coins there may have been examined less frequently
While requiring patience, roll hunting occasionally rewards searchers with valuable finds overlooked by previous handlers.
Authentication Considerations: Protecting Yourself from Mistakes
The high value of these coins has inevitably attracted counterfeiting and misidentification. Consider these authentication factors:
Common Counterfeits and Alterations
- 1916 Mercury dimes with added “D” mintmarks
- Regular proof coins with removed “S” mintmarks
- Artificially damaged coins mimicking errors
- Altered dates (especially converting 1946 dimes to 1942/1)
Professional Authentication
For potentially valuable discoveries:
- Third-party grading services like PCGS, NGC, and ANACS provide authentication and grading
- Encapsulation in a grading service holder significantly enhances marketability
- Authentication costs ($30-$100 per coin) represent a small investment for genuine rarities
Education as Protection
Knowledge remains the collector’s best defense:
- Reference books and online resources help identify diagnostic features
- Comparison with authenticated examples develops visual recognition skills
- Understanding manufacturing processes helps distinguish genuine errors from damage
