A routine clean-up of an old toolbox turned into a once-in-a-lifetime moment when a rare 1943 copper penny was discovered tucked between rusted screws and nails.
What looked like an ordinary coin at first turned out to be one of the most valuable and sought-after pennies in American history—now sold for $247,000 at auction.
The Mystery of the 1943 Copper Penny
In 1943, due to wartime needs, the U.S. Mint shifted from copper to zinc-coated steel for penny production. However, by accident, a small number of copper planchets from 1942 were still in the minting presses, resulting in a handful of 1943 copper pennies being made.
These coins were never meant to exist—and today, fewer than 20 confirmed examples are known. Because of their rarity and the intriguing error that created them, they are considered “holy grail” coins for collectors.

How It Was Found
The coin’s owner was helping clean out his grandfather’s garage when he stumbled upon an old metal toolbox. Among loose change, screws, and bolts lay a penny with a noticeably different color than others.
After noticing that it didn’t stick to a magnet and had a 1943 date, further testing confirmed it was indeed the rare copper variant from that year.
What Makes This Coin So Valuable?
The coin’s worth stems from three main factors:
- Extremely low mintage due to minting error
- High demand among numismatists and investors
- Condition and authenticity, especially if uncirculated or in mint state
Some versions, like the 1943 copper penny with a Denver (D) or San Francisco (S) mint mark, can be worth even more based on scarcity.
How to Tell If You Have One
Here’s a quick checklist to evaluate if your 1943 penny might be worth thousands:
- Check the date: It should say 1943.
- Use a magnet: If it sticks, it’s steel (not valuable). If not, it’s worth further inspection.
- Weigh it: A copper penny should weigh around 3.11 grams.
- Look for mint marks: No mark (Philadelphia), D (Denver), or S (San Francisco).
What To Do If You Think You Found One
If your penny passes the initial tests, your next step should be professional authentication and grading. This will certify the coin’s legitimacy, determine its condition, and provide an estimated value. Graded coins are much easier to sell and usually fetch higher prices at auction or through private sales.
The 1943 copper penny is a perfect example of how a small mistake in minting can result in one of the most valuable coins in American history. Found in a dusty toolbox, this humble cent turned into a $247,000 payday.
With just a few known in existence, this story serves as a powerful reminder—sometimes the greatest treasures are hiding in plain sight. So next time you’re cleaning out a drawer, attic, or garage… check your pennies.
