You might want to take a closer look at your spare change — especially those seemingly regular pennies. The 2001-D Lincoln cent mule error coin is one of the rarest and most valuable coins minted in recent history. At first glance, it looks like any other penny featuring Abraham Lincoln on the front. But flip it over, and instead of the Lincoln Memorial, you’ll find something that shouldn’t be there: the back of a Roosevelt dime.
Yep, that’s right — it’s a one-cent coin with the reverse side of a ten-cent coin. This kind of minting mistake is what collectors call a “mule error.” It happens when two dies from different denominations are mistakenly paired and struck onto a blank coin. In this case, the Denver Mint in 2001 somehow pressed the front of a penny with the back of a dime.
How much is the 2001-D Mule Penny worth?
Here’s the jaw-dropping part: this little copper-colored coin has sold twice at auction for over $100,000. You read that right — over one hundred grand for a coin you might accidentally overlook in your junk drawer.
Even more exciting? You don’t need a shiny, pristine version of this coin to make serious money. Reports say that even worn-out examples can sell for $20,000 or more, thanks to how incredibly rare this error is.
According to CoinWeek, “The 2001-D Lincoln cent mule falls in the category of Mint errors that conceivably could have been produced by mistake and released unnoticed into circulation.” So yes, it’s possible one of these coins is sitting in someone’s pocket right now, totally unrecognized.
How can you tell if you have the rare 2001-D Mule Penny?
Now the real question: how do you know if you have one of these? First, check the date and mintmark — it should read 2001-D on the front with Lincoln’s profile. Then flip it over and see if it has the back of a Roosevelt dime instead of the Lincoln Memorial. The dime reverse features a torch flanked by an olive branch and oak branch, along with the words “United States of America” and “One Dime.”
If that’s what you see on your penny — congratulations, you may be holding something worth tens of thousands.
