If you’ve got spare change lying around, this guide will show you exactly how to test and identify this transitional error — and maybe turn your penny into a life-changing treasure.
Why This 1982 Penny Is Worth $340,000
In 1982, the U.S. Mint changed the penny’s composition:
- Before 1982 → 95% copper (3.11 grams)
- After 1982 → Copper-plated zinc (2.5 grams)
The rare $340K penny is a mistake — struck on a leftover copper planchet at a time when the Mint had already switched to zinc.
Key facts about the $340,000 coin:
Struck at the Philadelphia Mint (no mint mark)
Made of solid copper, not zinc
Graded MS-67 Red (nearly flawless condition)
