The Mysterious WWII-Era Penny That Stumped Experts
A follower of @TheCoinChannel thought they’d found a $100,000+ 1943 copper penny — but PCGS revealed it’s even rarer: an experimental shell casing planchet penny, one of only 2–3 known to exist! Here’s why this coin is a game-changer for collectors.
🔎 What Makes This Penny So Special?
- Not Copper, Not Steel: Struck on a World War II shell casing planchet — exact metal composition remains classified.
- Weight Matches Copper: 3.11 grams, fooling collectors at first glance.
- Historic Significance: Likely a mint employee’s secret experiment during the metal shortage.
- Record Auction Sale: The only other known example sold for $167,000.
🕵️♂️ How to Spot Ultra-Rare Experimental Pennies
- Weigh It:
3.11g = could be copper or experimental metal. - Magnet Test:
Some experimental alloys may or may not be magnetic — inconsistent results. - Check Colors:
Shell-case pennies often show a dull gray or brassy tone, unlike typical copper or steel pennies. - Authentication:
Submit to PCGS or NGC for professional grading and verification.
⚠ What to Do If You Find One
- DO NOT CLEAN IT! Cleaning alters the metal’s surface chemistry and ruins value.
- Handle Carefully: Use cotton gloves to avoid oils damaging the experimental alloy.
- Insure Immediately: This is a high-value rarity needing specialist coverage.
