Coin collecting is more than just a hobby—it’s a treasure hunt! Some coins in circulation today are worth much more than their face value. Among them, two rare dimes and a Bicentennial quarter stand out, with one of these coins valued at an astonishing $15 million. Let’s look into the history and value of these elusive coins that could still be lurking in your pocket change.

Mercury Dime
The 1916-D Mercury Dime is one of the most sought-after coins among collectors. Minted in Denver, this dime is part of the Mercury Dime series, which ran from 1916 to 1945. The obverse features Lady Liberty wearing a winged cap, symbolizing freedom of thought.
What makes this dime so rare? The Denver Mint produced only 264,000 of them—the lowest mintage of the entire series. Because of its scarcity, a well-preserved 1916-D Mercury Dime can sell for tens of thousands of dollars, depending on its condition.
If you come across a Mercury Dime, check for a small “D” mintmark on the reverse side, just below the olive branch. If it’s a 1916-D, you may have found a fortune!
1945 Micro S Mercury Dime
Another rare dime from the Mercury series is the 1945 Micro S Mercury Dime. Unlike the 1916-D, this one wasn’t rare due to low mintage but because of a minting error.
The San Francisco Mint produced this dime, and some coins had a tiny “S” mintmark, now known as the Micro S variety. Though this was a mistake, it made the coin highly collectible. Depending on the condition, a 1945 Micro S Mercury Dime can be worth hundreds to thousands of dollars.
If you have a 1945 Mercury Dime, take a close look at the mintmark size—a smaller “S” could mean a valuable find!
Bicentennial Quarter
One of the most fascinating coin errors in history involves a 1976 Bicentennial Quarter. These quarters were released to commemorate 200 years of American independence, featuring a drummer on the reverse instead of the usual eagle.
But what makes one of these quarters worth $15 million? A rare minting error led to a Bicentennial Quarter being struck on a 1941 Canadian quarter. Somehow, a 1941 Canadian coin was mixed into the batch during production, creating a one-of-a-kind mistake.
This extremely rare coin is believed to still be in circulation, making it one of the most valuable coins you could ever find in your spare change. While the chances of observing this exact quarter are slim, it proves that errors can turn ordinary coins into extraordinary treasures.
How to Spot Rare Coins
If you want to start checking your change for rare coins, keep these tips in mind:
- Look for mintmarks: Coins from certain mints are rarer than others.
- Check for errors: Odd designs, off-center strikes, or double prints can mean extra value.
- Examine the date: Some years have extremely low mintage numbers, making them more valuable.
- Use a magnifying glass: Small details, like the Micro S mintmark, can be easy to miss.
| Coin Name | Year | Mintmark | Estimated Value |
|---|---|---|---|
| Mercury Dime | 1916 | D | Up to $50,000+ |
| Mercury Dime (Micro S) | 1945 | S | $200 – $1,000+ |
| Bicentennial Quarter | 1976 | Error (1941 Canadian) | $15 Million |
These rare finds remind us that treasures can still be hiding in plain sight. Whether you’re a seasoned collector or just getting started, always keep an eye on your change—you never know when you might stumble upon a fortune!
