The 6 Most Valuable Coins You Can Find in Your Change
1. 1943 Bronze Lincoln Cent
The 1943 Bronze Lincoln Cent is one of the rarest and most valuable coins ever minted in the U.S. Here’s why: In 1943, due to a shortage of copper during World War II, the U.S. Mint switched from using copper to zinc-coated steel for pennies. However, a few copper planchets were accidentally left in the production line, resulting in some rare 1943 bronze pennies.
These coins are worth far more than face value—in fact, one was sold for a staggering $336,000 in 2019 at auction. There are only about 20 to 40 of these coins known to exist, making them highly coveted by collectors. Finding one in your change would be incredibly rare, but it’s worth checking your pennies closely!
How to Spot It: Look for a 1943 penny that seems to be made of copper (not the typical steel color). If it’s copper-colored, you could be holding a rare find!
2. 1916-D Mercury Dime
The 1916-D Mercury Dime is one of the most sought-after coins in American numismatics. Minted in 1916, only 264,000 of these coins were produced at the Denver Mint. The low mintage makes the 1916-D Mercury Dime an exceptionally rare find. Even in good condition, this dime can fetch up to $250,000 at auction.
This coin is prized for its design and rarity. The obverse features the iconic image of Lady Liberty wearing a winged cap, while the reverse displays a Roman fasces (a bundle of rods with an axe). It’s considered a masterpiece of U.S. coin design.
How to Spot It: Look for a dime from 1916 with the mintmark “D” (for Denver) beneath the “IN GOD WE TRUST” inscription. If it’s a 1916-D, you’ve got a treasure on your hands!
3. 1975 No-S Proof Dime
In 1975, a mistake occurred when a small number of proof dimes were struck without the “S” mintmark, which was supposed to indicate they were produced at the San Francisco Mint. This error made the 1975 No-S Proof Dime an instant collector’s item. Only a few examples are known to exist, and one of these rare coins fetched a jaw-dropping $456,000 at auction in 2019.
How to Spot It: Look closely at the reverse side of a 1975 proof dime. If it doesn’t have the “S” mintmark (which is usually on the bottom of the coin), you could have found one of the rarest dimes ever minted.
4. 1894-S Barber Dime
The 1894-S Barber Dime is another incredibly rare coin. In fact, only 24 of these coins were minted, and today only nine are known to exist. The story behind this coin is fascinating—most of the 1894-S Barber Dimes were lost, and only a handful were preserved.
One of these dimes sold for nearly $2 million at auction, making it one of the most valuable U.S. dimes in existence. Finding one in circulation would be next to impossible, but if you happen to inherit or stumble upon one, you could be holding a piece of U.S. history worth millions.
How to Spot It: The 1894-S Barber Dime has a distinct design by Charles E. Barber, with Liberty’s head on the obverse and a wreath of olive branches on the reverse. The mintmark “S” is located beneath the “D” in “DIME.”
5. 1942/1 Mercury Dime
This is another example of a coin with a minting error. The 1942/1 Mercury Dime was struck using a 1941 die that had been re-engraved to read “1942,” leaving traces of the original “1” from the previous year. This overdate error makes the 1942/1 Mercury Dime an extremely valuable coin, with some selling for over $100,000 in recent years.
How to Spot It: Look at the “1942” date on the coin closely. If you can spot a small “1” under the second digit, it’s a 1942/1 overdate error coin, which is worth a lot more than the standard 1942 Mercury Dime.
6. Bicentennial Quarters (1975-1976)
You’ve probably come across Bicentennial Quarters in your change—they were minted to commemorate the United States’ 200th anniversary. But did you know that some Bicentennial Quarters are worth more than just 25 cents? Certain versions, especially those with minting errors or rare characteristics, can fetch up to $19,200 at auction.
How to Spot It: While most Bicentennial Quarters are worth face value, you should pay attention to any that have unique features or errors, such as doubling in the design or unusual minting flaws. Keep an eye on rare examples with these characteristics.
The Importance of Coin Collecting
Coin collecting is more than just a fun hobby—it’s also an investment opportunity. As you’ve seen, some coins can be worth significantly more than their face value. Over time, as fewer coins are available, their rarity increases, and their value grows.
For beginners, it’s a great idea to start by collecting coins that interest you or relate to a particular theme, such as U.S. history, famous figures, or even popular movie franchises. For professionals, however, it’s all about quality and rarity. Coins with errors or limited mintage numbers often see their value soar as time passes.
How to Protect Your Coins
If you’re lucky enough to have discovered a valuable coin, it’s important to take proper care of it. Coins are susceptible to damage from handling, exposure to elements, and even storage in improper conditions. Here’s how to protect your collection:
- Store Coins in Protective Sleeves: Use acid-free holders like 2×2 holders, capsules, or albums to keep your coins safe from dirt and wear.
- Avoid Cleaning Your Coins: Cleaning coins can reduce their value by scratching or damaging the surface. If a coin needs cleaning, it’s best to have it professionally cleaned.
- Use Gloves When Handling Coins: Always wear cotton gloves when handling rare or valuable coins to avoid transferring oils and dirt from your fingers.
The History Behind These Rare Coins
The history of these valuable coins is rich and often tied to key events in U.S. history. For example, the 1943 Bronze Lincoln Cent is a direct result of World War II, when copper was in short supply and the U.S. Mint had to quickly pivot to a steel-based penny. Meanwhile, the 1894-S Barber Dime represents a time when coinage designs were undergoing significant changes, with Charles E. Barber’s designs becoming iconic.
Understanding the context behind each coin can give you a deeper appreciation for their rarity and why they’re so valuable.
Other Coins Worth Looking Out For
While the coins mentioned above are among the most valuable, there are many other rare and valuable coins worth checking for:
- 1955 Double Die Lincoln Cent: Known for its noticeable doubling of the date, it can fetch up to $1,000 in high grade.
- 1937-D Three-Legged Buffalo Nickel: A minting error that makes the buffalo appear to have only three legs, this coin can be worth thousands.
- 2000-P Sacagawea Dollar: Some versions have the famous “Cheerios” error, making them quite valuable.
