The Ultimate Guide to America’s Rarest Cent
🏆 The Legend of the 1943 Copper Penny
At PennyVerse, we’ve handled some of the rarest coins on Earth — but few rival the 1943 copper Lincoln cent.
During WWII, pennies were supposed to be made from steel to conserve copper for the war effort. But a small batch of copper planchets was accidentally used, creating one of the most famous and valuable U.S. coin errors in history.
With only 10–15 known examples, this “holy grail” coin could be sitting unnoticed in your collection right now. Here’s how to tell if you have the real deal.
🔍 3 Telltale Signs of a Genuine 1943 Copper Penny
1️⃣ The Magnet Test 🧲
- Real Copper: Won’t stick to a magnet
- Normal 1943 Steel: Strong magnetic pull
2️⃣ Precision Weight Verification ⚖️
- Authentic: 3.11 grams (same as normal copper cents)
- Fake or Altered: Around 2.7 grams (steel weight)
💡 Pro Tip: Use a digital jewelry scale with 0.01g accuracy for best results.
3️⃣ Date Examination (10x Magnification) 🔎
- Genuine 1943: The “3” sits slightly lower than the “4”
- Altered 1948: The “3” is level with the “4” (common fake)
