Sometimes, the U.S. Mint makes mistakes—and while these errors might seem small, they turn ordinary coins into unique, valuable collectibles that can fetch big bucks from coin collectors.
These “error coins” come from slight slips during production, and their quirky imperfections make them rare finds that collectors crave. Here are 12 U.S. coin mistakes that could turn your spare change into a fortune!
1. 1955 Double Die Lincoln Penny
This is one of the most famous U.S. error coins. The 1955 Lincoln penny has a noticeable “double die” error, where the year and the word “Liberty” appear doubled. This occurred due to a misalignment in the minting process. If you find one, it could be worth $1,000 to $15,000 based on its condition!
2. 1943 Copper Penny
During World War II, the Mint switched to steel for pennies to save copper. However, a few copper pennies were accidentally made. These rare 1943 copper pennies are highly valued, with some selling for over $200,000 at auctions.
3. 1970-S Small Date Lincoln Cent with Doubled Die
This Lincoln penny, minted in San Francisco, has a double-die error and a smaller date size. The subtle doubling in “Liberty” and “In God We Trust” makes it highly collectible. Its rarity could make it worth a few thousand dollars to dedicated collectors.
4. 1969-S Doubled Die Lincoln Cent
Similar to the 1955 double-die penny, this 1969 penny shows a clear doubling in the date and “Liberty.” The error was caught early on, so only a limited number were circulated, making it worth as much as $70,000 for collectors.
5. 2004 Wisconsin State Quarter with Extra Leaf
The 2004 Wisconsin quarter features an unusual “extra leaf” on the corn’s design, which was likely an accidental addition. Two versions exist—the “high leaf” and “low leaf” variations, with some selling for up to $2,000.
6. 1999 Wide “AM” Penny
Look closely at the “AMERICA” on this 1999 penny—if the “A” and “M” are spaced wider than usual, you’ve found a valuable variant. These are rare, and collectors have been known to pay hundreds of dollars for them.
7. 1982 No Mint Mark Roosevelt Dime
Dimes typically have a mint mark indicating where they were produced. In 1982, some dimes were mistakenly produced without a mint mark, making them rare. Top-condition versions have sold for up to $300.

9. 1972 Doubled Die Obverse Penny

10. 2000 Sacagawea Dollar with a “Cheerios” Pattern
Known as the “Cheerios Dollar,” this version of the 2000 Sacagawea dollar has a unique feather pattern on the eagle. These special dollars were originally part of a Cheerios promotion, and they can sell for up to $5,000 today.
11. 1950-D Jefferson Nickel
Though not a true error, the 1950-D Jefferson nickel has one of the lowest mintages and is highly prized by collectors. Mint-condition examples have sold for up to $15,000, making it a valuable find.
12. 1983 “Spitting Eagle” Quarter
Some 1983 quarters show a die crack near the eagle’s beak, giving the impression it’s “spitting.” This small defect has turned it into a collector’s item, with values reaching a few hundred dollars.
