Mule Error Coins are some of the coolest and rarest coins you can find. They’re mistakes made at the U.S. Mint—but not just any mistake. These coins happen when two parts from different coins get put together by accident. The result? A rare and super valuable coin that collectors love.
What Is a Mule Coin?
A mule coin is made when the front (called the obverse) of one coin is combined with the back (called the reverse) of another coin. These two designs were never meant to be used together, so the coin ends up looking very strange—and very special.
Just like how a mule (the animal) is a mix between a horse and a donkey, a mule coin is a mix between two different coins.
How Do Mule Coins Happen?
Mule coins are not planned. They’re created by mistake at the mint when a worker accidentally uses the wrong dies (the metal stamps that press the designs onto coins). For example, one time the front of a Sacagawea dollar was paired with the back of a Washington quarter. That wasn’t supposed to happen, but it created a coin worth thousands of dollars!
Types of Mule Coins
There are a few different kinds of mule coins:
- Obverse-Reverse Mule: The front and back come from two different coins (this is the most common kind of mule).
- Double Obverse or Double Reverse Mule: These coins have either two fronts or two backs. They’re even rarer!
Famous Mule Coins
Here are some well-known examples:
- 2000-P Sacagawea Dollar/Washington Quarter Mule
This is one of the most famous mule coins. Only about 20 are known to exist. It can sell for $100,000 to $125,000! - 2001-D Lincoln Cent/Roosevelt Dime Mule
This coin has the front of a penny and the back of a dime. One sold for $114,000 in 2021.
Why Are Mule Coins So Valuable?
These coins are worth a lot because:
- They are very rare.
- They were made by mistake, which makes them special.
- They’re hard to fake and easy to spot if you know what to look for.
Collectors love these kinds of coins because they tell a cool story about what can go wrong during the minting process.
