4-Step Authentication Checklist
Follow these steps before celebrating your discovery
Verify the Weight
Use a precise digital scale: 3.11g = copper, 2.5g = zinc.
Perform a Magnet Test
Copper is non-magnetic. If it sticks to a magnet, it’s fake or plated.
Examine the Date
Compare the “2” — on the Small Date, it has a delicate curve at the base instead of a flat line.
Get Professional Grading
Submit your coin to PCGS or NGC for official verification and value protection.
Only certified coins reach top auction prices.
Why This Penny Is Worth Nearly $400,000
Mint Error Miracle – Denver wasn’t supposed to strike any copper cents in 1982.
Historical Importance – Marks the end of the copper penny era.
Ultra Rarity – Only a handful of survivors exist, all highly graded.
It’s the perfect mix of history, rarity, and collector obsession — which is why this coin keeps setting records.
Critical Warnings for Collectors
Plated Zinc Fakes: Many forgeries are made by coating zinc pennies in copper.
Incorrect Weight: Must read exactly 3.11g — no exceptions.
Uncertified Listings: Always insist on PCGS/NGC certification before buying or selling.
Even a small deviation can turn a $398,000 dream into a $0 fake.
