Every so often, a discovery shakes the coin collecting world. Recently, a certified 1942 Lincoln cent struck on a foreign planchet surfaced — and it’s already estimated to be worth $75,000 to six figures at auction.
What Makes This 1942 Penny Special?
Normally, Lincoln cents struck in 1942 were made of 95% copper and 5% zinc/tin and weighed about 3.11 grams. But this coin weighed only 2.5 grams, far too light for a U.S. penny.
After analysis, experts confirmed it was mistakenly struck on a foreign planchet from Curaçao (Netherlands). The U.S. Mint was striking coins for several countries during World War II, and occasionally, a wrong planchet slipped into the presses.
How to Identify the Error
If you think you’ve found a rare off-metal error:
- Weigh the Coin – A genuine 1942 cent should weigh about 3.11 grams. If it’s much lighter or heavier, it could be on the wrong planchet.
- Check the Size and Color – Planchets from other nations often have slightly different diameters or tones.
- Look for Weak Details – When struck on an undersized or foreign planchet, design elements may appear off-center, stretched, or incomplete.
- Seek Certification – Only PCGS or NGC can confirm authenticity and assign a market value.
Value of the 1942 Curaçao Off-Metal Penny
- Typical 1942 cent: 1 cent
- 1942 Curaçao planchet error: $75,000–$100,000+ depending on condition and demand
Auction houses like Heritage and Stack’s Bowers handle these kinds of high-value sales, and bidding wars often drive prices even higher.
Why Collectors Pay Big Money

✔️ Major Mint Error: Wrong-planchet errors are among the rarest in U.S. numismatics.
✔️ Scarcity: Only a handful of Curaçao-planchet cents are known to exist.

💡 Tip: If you ever find a coin that feels too light, too heavy, or looks odd — don’t dismiss it! Off-metal errors like this can turn spare change into life-changing money.
