For most, spare change is money they toss into jars or in car consoles with no second glance. But imagine if one of those coins actually was worth millions of dollars. Sounds far-fetched, correct? Yet that’s precisely what’s true for a few very rare U.S. dimes and one amazing Bicentennial quarter totalling an estimated $17 million apiece.
These seemingly ordinary coins are hiding incredible value due to minting errors, limited production runs, and historical significance. In this article, we’ll break down the five rare dimes and one Bicentennial quarter that could make you an instant millionaire.
1. The 1894-S Barber Dime
Arguably the most legendary dime ever minted, the 1894-S Barber Dime is a crown jewel in coin collecting.

Key Facts:
- Only 24 were ever minted.
- Thought to have been produced for a special purpose, such as gifts for the VIPs or for testing.
- Fewer than 10 remain today.
- One is known to have sold for more than $1.9 million in 2016.
If you ever come across a dime dated 1894 with an “S” mint mark (for San Francisco), don’t spend it—it may pay for your retirement and then some.
2. 1916-D Mercury Dime
The 1916-D Mercury Dime is another scarce beauty, characterized by its low mintage and high collectibility.
Key Facts:
- Only 264,000 were produced in Denver.
- Highly coveted, particularly in uncirculated condition.
- Can bring more than $200,000–$1 million based on grade.
Numerous Mercury dimes were manufactured in 1916, but the Denver one is extremely rare. Look for a tiny “D” mint mark on the back.
3. 1942/41 Mercury Dime (Overdate Error)
The 1942/41 overdate error dime is a dream for collectors a minting blunder that led to double printing of numbers on the coin.
Key Facts:
- The “2” over a “1” in the date makes for a distinct double impression.
- It is found in both Philadelphia (no mint mark) and Denver (D mint mark) versions.
- High-grade examples can command $100,000 or higher.
It’s a small mistake but one that increases value by millions. Use a jeweller’s loupe or magnifying glass to look over your coins up close.
4. 1874-CC Liberty Seated Dime
From the Carson City Mint, the 1874-CC Liberty Seated Dime is worth money based on its survival rate and western frontier origin.
Key Facts:
- Only 10,817 were produced.
- Very few have been made in nice condition.
- Worth up to $500,000 or higher.
Collectors are attracted to coins issued by the currently closed Carson City Mint due to their rarity and historical significance. If you spot “CC” on the reverse of a Liberty Seated dime, you will want to hold on to it.
5. 1982 No-P Roosevelt Dime
This coin indicates that even newly minted dimes can turn out to be a fortune if there was some error made at the mint.
Key Facts:
- In 1982, the Philadelphia Mint misplaced the “P” mint mark on some of the dimes.
- These mint-mark-less coins are scarce and very valuable.
- The high-grade specimen can fetch $75,000–$150,000.
The error in omitting the mint mark was a mistake, but it’s now a prise for clever collectors.
6. The Bicentennial Quarter Error Coin
The Bicentennial quarter of 1976 was issued to commemorate 200 years since American independence. Although millions were produced, a few scarce ones are now worth millions.

Key Facts:
- The scarce ones are likely mint errors, including:
- Struck on a silver planchet that was not intended for circulation
- Double die obverse (doubled images or letters)
- Off-center strikes or other distortions
It has been estimated by some experts that one or more of these have appeared in private auctions for as much as $17 million. A majority of Bicentennial quarters are plentiful, but if you’re lucky enough to come across one with unusual features particularly in mint condition have it authenticated.
How to Identify These Rare Coins
If you’re already itching to rummage through your change jar, here are some fast facts on how to identify these elusive coins:
- Check the date and mint mark—the little letter on the reverse of the coin (most often near the bottom) tells you where it was made.
- Employ a magnifying glass—numerous collector coins possess minor minting flaws that are difficult to observe without a magnifying glass.
- Compare with online photos—trustworthy numismatic websites such as PCGS and NGC carry close-up pictures of what rare coins are supposed to look like.
- Inspect the condition—uncirculated or mint-state coins are worth much more than worn-out coins.
What To Do If You Think You Have One
Discovered something promising? Don’t attempt to auction it on eBay just yet. Here’s what you can do:
- Have it graded and authenticated—use companies such as PCGS or NGC. They will authenticate the coin and grade it.
- Check with a trusted dealer—search for licenced numismatists who belong to the American Numismatic Association (ANA).
- Don’t clean the coin—cleaning can hurt the surface of the coin and devalue it.
