Everything to know about double die pennies

Double die pennies are a fascinating occurrence in the world of coin collecting, sparking interest among professional coin collectors and hobbyists alike. These coins are celebrated for their unique errors that occur during the minting process, making each one a rare and valuable treasure.

What is a double die penny?

A double die penny is the result of a minting error where the die used to strike the coin imprints the design more than once in slightly different positions. This misalignment creates a doubled or overlapping appearance on parts of the coin. Their uniqueness makes them highly desirable, and their value can range significantly depending on the extent and visibility of the error, as well as the coin's condition.

While commonly mistaken for double-struck coins, double die coins are different. Double-struck coins have been struck twice by the coin press, whereas double die coins result from errors in the die itself.
