About This Coin

In 1943, the U.S. minted pennies from steel to conserve copper for World War II. However, a few copper planchets from 1942 remained in the press, creating one of the most valuable mint errors - the 1943 copper penny.

Identification Tips

Use a magnet! Steel 1943 pennies (common) are magnetic. Copper pennies (rare) are NOT magnetic. Check the weight - copper weighs 3.11g, steel weighs 2.7g. Color should be copper, not gray. Many fakes exist - either copper-plated steel or altered dates. Professional authentication is ESSENTIAL before spending serious money.

Historical Context

During WWII, copper was critically needed for ammunition and military equipment. The mint switched to zinc-coated steel for pennies in 1943. However, a handful of copper planchets left in the presses from 1942 production accidentally received 1943 dies, creating these legendary errors. Only about 15-20 genuine examples are confirmed across all mints.
