Coin collecting, also known as numismatics, is more than just finding rare coins. Some everyday coins become incredibly valuable due to minting errors—mistakes made during the coin-making process. These errors are rare but can turn ordinary coins into treasures worth thousands or even millions. Let’s explore 12 fascinating mint errors that transformed regular coins into extraordinary collectibles.

- Value: $1,000–$25,000 (depending on condition)
