Posted by In a story that feels pulled from a movie script, a 1943 Lincoln penny once used in a middle school science project has shocked the coin-collecting world by selling for over $10,000. What was once just a teaching aid for a magnetism lesson is now a rare and valuable piece of American history.
The Science Project That Sparked It All
Years ago, an eighth-grade science teacher included a handful of coins in a classroom demonstration on magnetism and metals. Among the paper clips and nails was a dirty, unassuming 1943 penny.
The coin didn’t stick to a magnet, which the class found odd—but nobody thought much of it. It was placed in a plastic bag and stored with other school supplies, forgotten for decades.
Fast forward to spring cleaning in 2025. That same teacher, now retired, found the bag and noticed the 1943 date. Knowing that year was unique in penny history, they decided to have it appraised. What came next left everyone stunned.
Why Is This 1943 Lincoln Penny Worth So Much?
During World War II, copper was reserved for military needs like shell casings and communications wiring. So, in 1943, the U.S. Mint began producing pennies from zinc-coated steel instead of copper.
However, by accident, a few copper blanks—known as planchets—were left in the minting presses. These resulted in a handful of 1943 copper pennies, which are now among the rarest and most valuable coins in U.S. history.
Less than 20 authentic specimens are believed to exist. This makes them extremely desirable to collectors.
Quick Comparison : 1943 Pennies
| Coin Type | Metal Composition | Magnetic? | Estimated Value |
|---|---|---|---|
| 1943 Steel Penny | Zinc-coated Steel | Yes | Under $1 |
| 1943 Copper Penny | 95% Copper, 5% Zinc | No | $10,000 to over $100,000+ |
Rediscovery and Authentication
The coin, still a bit grimy from its classroom days, was sent for authentication. Specialists measured the weight (3.11 grams) and confirmed the coin’s non-magnetic nature—both tell-tale signs of a copper planchet.
Once authenticated, interest from collectors surged. The penny was later auctioned privately, selling for an estimated $15,000–$18,000, depending on condition and collector demand.

What Makes a Coin Valuable?
There are several factors that can turn pocket change into a payday:
- Metal Composition: Coins made from rare or unexpected metals stand out.
- Mint Errors: Misprints, off-center strikes, and wrong planchets can be goldmines.
- Historical Context: Coins produced during significant historical periods are more collectible.
- Condition: Coins with minimal wear hold much higher value.
How to Check Your Own Change
If you’re curious whether you’ve got a fortune hiding in your coin jar, look for:
- 1943 Pennies that are not magnetic
- Coins that appear copper-colored but say 1943
- Unusual weights (real copper pennies weigh 3.11 grams)
If you find anything suspicious, take it to a professional appraiser for verification.
This one-of-a-kind story proves that extraordinary value can hide in the most ordinary places. What started as a forgotten school science project ended as a $10,000+ windfall, simply because someone took the time to look closer.
Whether you’re a seasoned collector or just curious, it might be time to check your change—there could be a treasure hiding in plain sight.
FAQs
How can I tell if I have a 1943 copper penny?
Check if it sticks to a magnet. If it doesn’t, and it looks copper-colored, weigh it—3.11 grams may indicate copper.
