Imagine turning a single penny into $340,000. 😲 That’s exactly what happened when a rare 1982 Lincoln cent error sold at auction for a life-changing sum.
This isn’t just pocket change — it’s one of the most valuable transitional error coins ever discovered. Here’s how to spot, test, and protect this copper treasure.
💎 Why the 1982 Penny Is So Valuable
In 1982, the U.S. Mint changed the composition of pennies:
- Before 1982: 95% copper, weighing 3.11 grams
- After 1982: Copper-plated zinc, weighing 2.5 grams
The $340,000 penny was a mistake — struck on a leftover copper planchet after the mint had already switched to zinc. Only a handful exist, making it a collector’s dream.
✅ Key Facts About the $340K Penny
- No mint mark (Philadelphia Mint)
- Made of solid copper instead of zinc
- Graded Mint State 67 Red (MS67RD) 🏆
- Only 5–10 coins known to exist
