Have you ever checked your spare change carefully? Some nickels—worth just 5 cents—could actually be worth thousands or even millions due to rare minting errors!
These mistakes happened when the U.S. Mint accidentally released coins with flaws. Today, collectors pay huge money for them.
Let’s explore 10 rare nickel errors that might still be hiding in your pocket!
1. 1937-D Three-Legged Buffalo Nickel
Why It’s Valuable
A mint worker polished the coin die too much, erasing one of the buffalo’s legs!
