The $29,250 1983 Copper Penny: How to Spot This Rare Minting Mistake


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

  • 2.5 grams = common, no extra value
  • 3.1 grams = rare copper error, potentially worth thousands

Step 3: Condition Matters

  • Mint State 65 (MS65) examples can sell for $20K–$30K
  • Even circulated examples can fetch $4,000–$5,000

The Record-Breaking Auction

  • Auction Price: $29,250
  • Grade: PCGS MS65
  • Rarity: Only a small number confirmed to exist

Pro Tips for Collectors

  1. Always weigh 1983 pennies—a simple digital scale can reveal a fortune.
  2. Never clean the coin—cleaning can destroy its numismatic value.
  3. Get professional grading—PCGS or NGC certification is essential for maximum value.

💎 Bottom Line: If your 1983 penny weighs 3.1 grams, you may be holding a coin worth more than a brand-new car. Start checking your change jars—you could be the next record-breaking seller.
