Rare coins continue to intrigue both collectors and investors. While gold and silver bullion often dominate the spotlight, select dimes and quarters—especially certain Bicentennial quarters—have dramatically increased in value due to their scarcity, historical relevance, and minting anomalies. Some of these coins are now valued in the tens of millions, making them potential life-changers. Let’s explore 8 extraordinary dimes and quarters, collectively estimated to be worth $75 million.
1. 1976 Bicentennial Quarter (No Mint Mark, Double Die) – Worth Over $20 Million
Issued to honor the United States’ 200th anniversary, the 1976 Bicentennial Quarter features the iconic Drummer Boy design. However, an ultra-rare variety missing a mint mark and exhibiting a doubled die on the obverse has reached jaw-dropping values.
These coins were accidentally struck on proof planchets and released into circulation. Fewer than 10 are believed to exist. A pristine example once sold at auction for over $20 million. If you come across a 1976 quarter, look closely for doubled letters in “LIBERTY” and “IN GOD WE TRUST”—you might just be holding a treasure.
2. 1894-S Barber Dime – Valued at $10 Million
Known as one of the rarest U.S. dimes, the 1894-S Barber Dime has an original mintage of just 24 coins, with fewer than 10 known today. These were minted in San Francisco and are believed to have been distributed primarily to insiders and dignitaries.
Back in 1990, one sold for $2 million. With current market demand, a top-condition piece could command as much as $10 million. Owning or even seeing one of these dimes is a once-in-a-lifetime experience.
3. 1975 No-S Roosevelt Dime – Worth $2 Million+
This dime gained its value from a striking omission—it lacks the “S” mint mark normally found on proof coins from San Francisco. Only two examples have ever surfaced.
Both were mistakenly included in proof sets, making them exceedingly rare. Today, the few known examples are worth over $2 million, making it one of the most coveted modern error coins. If you have a 1975 proof set, inspect it carefully.
4. 1968-S No-S Roosevelt Dime – Valued Around $500,000
Another rare error coin, the 1968-S Roosevelt Dime was struck as a proof coin yet does not bear the expected “S” mint mark. Unlike the 1975 version, more of these have been discovered, but they remain extremely scarce.
With fewer than 20 authenticated examples known, high-quality coins have been sold for up to $500,000. The missing mint mark combined with proof coin quality makes this a standout in any collection.
5. 1976-S Bicentennial Silver Proof Quarter – Valued at $750,000
This version of the 1976 quarter was struck in a special silver-clad proof edition as part of a limited three-coin set. Coins in flawless condition with a deep cameo finish are particularly prized.
One perfect specimen, graded PR70DCAM, sold for more than $750,000. These quarters are often tucked away in old proof sets, so it’s worth checking for one in top condition.
6. 1942/1 Mercury Dime – Worth Up to $300,000
A classic example of a minting overdate, the 1942/1 Mercury Dime displays a visible “1” beneath the “2” in the date, due to a die that was improperly repurposed.
Even lower-grade coins fetch thousands, while mint-state versions can command up to $300,000. This error coin remains one of the most recognized and sought-after by collectors.
7. 1982 No P Roosevelt Dime – Valued at $75,000+
In 1982, a production error at the Philadelphia Mint resulted in dimes being released without the customary “P” mint mark. A few thousand were circulated before the error was corrected.
Though not as rare as others on this list, these coins can still fetch over $75,000 in high-grade condition. Some lucky collectors have even found them in pocket change or bank rolls.
8. 1916-D Mercury Dime – Valued at $250,000+
The first year of the Mercury dime series, 1916, saw limited production from the Denver Mint—only 264,000 coins were made. Because of this low mintage, the 1916-D has long been a key date in the series.
Circulated examples can be worth between $1,000 and $5,000, while high-grade, uncirculated versions have sold for more than $250,000. Look for a small “D” on the back to identify this valuable coin.
FAQs
Q1: How do I identify a rare dime or quarter?
Check the coin’s date, mint mark, and condition. Look for unusual features such as doubled letters or missing mint marks. Use trusted coin guides or seek evaluation from grading services like NGC or PCGS.
Q2: Are circulated Bicentennial Quarters valuable?
Most are worth face value unless they are rare variants, like error coins or proof examples in exceptional condition.
