In the world of coin collecting, some coins are far more than just old change. They’re historical artifacts, minting anomalies, and in some cases, million-dollar treasures.
Whether it’s a dime from the 1800s or a bicentennial quarter with a minting error, these rare finds have fascinated collectors and driven jaw-dropping auction prices.
Let’s take a look at 10 of the most sought-after dimes and bicentennial quarters that, together, could be worth as much as $75 million.
1894-S Barber Dime
Considered the holy grail of dimes, the 1894-S Barber Dime is extremely rare, with only 24 ever minted and fewer than 10 known to still exist. One story says a Mint Superintendent gave a few to friends—and even his daughter, who famously spent hers on ice cream. Today, surviving examples in good condition can bring over $2 million at auction.
1916-D Mercury Dime
Minted in Denver in the first year of the Mercury Dime series, only 264,000 of the 1916-D Mercury Dimes were produced. For comparison, most coins are minted in the millions. In uncirculated condition, this dime can be worth more than $100,000.
1942/1 Mercury Dime Overdate
This wartime error happened when dies initially engraved with 1941 were re-engraved for 1942, creating a visible overlap of the two years. Known as an overdate error, these dimes in high grade have sold for tens of thousands of dollars.
1975 No S Proof Roosevelt Dime
This modern rarity is a result of a proof coin being struck without the “S” mint mark from the San Francisco Mint. Only two are confirmed to exist. One sold in 2019 for $456,000, making it one of the most valuable modern coins.
1968 No S Proof Roosevelt Dime
Similar to the 1975 version, this proof dime was also struck without the “S” mint mark. Although not quite as rare, it’s still a major mint error, and collectors are willing to pay tens of thousands for one in excellent condition.
1976 Bicentennial Quarter
Celebrating America’s 200th birthday, the 1976 Bicentennial Quarter featured a colonial drummer design. Most aren’t worth more than 25 cents, but rare versions, mint errors, and proof strikes can be highly valuable.
1976-S Silver Proof Bicentennial Quarter
These quarters were minted in 40% silver by the San Francisco Mint and included in special collector sets. They have a brilliant, mirror-like finish and can be worth several hundred dollars in top condition.
1976 Quarter on Dime Planchet
This unusual mint error happened when a quarter design was accidentally struck on a dime-sized blank. Because of the size difference, the design appears off-center and incomplete. These major errors can fetch thousands of dollars when found.
1976-D Doubled Die Obverse Quarter
This error quarter shows doubling on the date and some lettering—caused by the die receiving a double impression. While not as dramatic in value, these still bring in hundreds or even thousands in pristine condition.
1976 Aluminum Bicentennial Quarter
Here’s the coin that may not even exist—or may be hiding in a collection somewhere. During the 1970s, the U.S. Mint experimented with aluminum coins due to rising metal costs.
A 1976 aluminum quarter was reportedly struck as part of these trials. If one ever surfaces and is legal to own, experts estimate its value could be in the millions.
These coins are more than just currency—they’re time capsules, errors, and rare creations that tell a piece of American history.
Whether you’re a seasoned collector or just found something interesting in your change jar, these dimes and quarters prove that sometimes, small things really can be worth a fortune.
