Why This 1983 Penny Sold for Over $29,000
Most 1983 pennies are worth face value—unless they have one critical difference: their weight.
- Standard 1983 penny: 2.5 grams (zinc composition)
- Rare error version: 3.1 grams (copper composition)
The heavier copper version exists because in 1983, the U.S. Mint had fully switched from copper to zinc planchets—but a few leftover copper blanks were accidentally struck.
How to Identify the Rare 1983 Copper Penny
Step 1: Check the Date
- Must be 1983 (no mint mark or “D” mint mark acceptable)
Step 2: Weigh the Coin

- 3.1 grams = rare copper error, potentially worth thousands
Step 3: Condition Matters

- Even circulated examples can fetch $4,000–$5,000
