The Stunning Truth Behind the Ultra-Rare 1974 Aluminum Penny – And How to Spot One
Could a penny in your pocket really be worth $12 million? It sounds like fiction — but this legendary coin is real, unbelievably rare, and still pops up in the most unexpected places. Here’s everything you need to know about one of the most valuable modern U.S. coins.
Why the 1974 Aluminum Penny Is So Special
In 1974, the U.S. Mint experimented with striking pennies in aluminum instead of copper to cut costs. Over 1.5 million aluminum cents were reportedly produced — but nearly all were recalled and melted before release.
Except a few.
A handful of examples escaped destruction, and today they’re among the most coveted U.S. rarities.
