If you’ve got an old coin jar sitting around collecting dust, you might be sitting on a treasure trove without even knowing it. In the world of numismatics (that’s just a fancy word for coin collecting), a few rare dimes and quarters stand out not only for their age or design but for their staggering value.
Let’s look into ten coins that, together, could be worth a jaw-dropping $75 million.

1894-S Barber Dime
This one’s the crown jewel of rare dimes. The 1894-S Barber Dime isn’t just rare—it’s legendary. Only 24 were ever minted, and fewer than 10 are known to exist today.
One popular story says the Mint Superintendent gave a few away to friends and even handed one to his daughter—who spent it on ice cream! In good condition, this coin can fetch over $2 million at auction.
1916-D Mercury Dime
Next, we’ve got the 1916-D Mercury Dime—a first-year release from the Denver Mint. Only 264,000 were struck, making it a must-have for collectors. If you’ve got one in mint condition, you’re looking at a coin worth $100,000 or more. It’s a classic example of how a small mintage number can lead to a big price tag.
1942/1 Mercury Dime
Here’s one born from a minting mistake: the 1942/1 Mercury Dime. During WWII, a die meant for 1941 was repurposed for 1942, leaving a ghostly “1” beneath the “2”. These overdates are big among error collectors and can sell for tens of thousands, especially in high grades.
1975 No-S
Jumping ahead in time, we hit the 1975 No S Proof Roosevelt Dime. What makes it so special? It was supposed to have an “S” mint mark for San Francisco, but someone forgot. Only two known examples exist. One sold for $456,000 in 2019. It’s modern, it’s rare, and it’s insanely valuable.
1968 No-S
Sound familiar? Just like in 1975, the 1968 No S Proof Roosevelt Dime had its mint mark accidentally omitted. These are more common than the ’75 version but still fetch serious cash—up to $20,000 or more, depending on condition. It’s another case of a tiny error creating huge value.
1976 Bicentennial Quarter
Let’s shift gears to the 1976 Bicentennial Quarter. While most of these are worth exactly 25 cents, a few rare versions are worth a lot more. The standard version features a drummer boy and was part of the U.S. Bicentennial celebration. Millions were minted, but keep reading for the special ones.
1976-S Silver
The 1976-S Silver Proof Quarter was minted in San Francisco with 40% silver. These shiny collectibles were sold in special proof sets and can be worth a few hundred dollars in pristine condition. Not ultra-rare, but a solid find for casual collectors.
Dime Planchet
Now here’s where things get weird: a 1976 Bicentennial Quarter struck on a dime planchet. That’s right—this quarter design ended up on a dime-sized blank, making it both smaller and lighter than normal. These mint errors are extremely rare and can sell for several thousand dollars.
Doubled Die
The 1976-D Doubled Die Obverse Quarter is another error coin worth mentioning. It has visible doubling on the date and lettering, making it a fun find if you’ve got sharp eyes.
Depending on its condition, it could bring in a few hundred to a couple thousand bucks.
Aluminum Test
Finally, the unicorn of quarters: the 1976 Aluminum Bicentennial Quarter. Officially, this coin doesn’t exist. It was part of an experimental run when the Mint was testing cheaper metals.
None were ever released—at least not legally. If one were to surface and be legal to own? Experts say it could be worth millions.

After all, these coins aren’t just currency—they’re history in your hand.
