$375,000–$1.7 MILLION 1943
Imagine finding a penny in your collection worth $375,000… or even $1.7 million 
That’s exactly what the legendary 1943 Copper Lincoln Cent represents — one of the rarest and most valuable mint errors in U.S. history.
Only a handful are confirmed to exist worldwide.
Let’s break it down step by step so you know exactly what to look for.
Why the 1943 Copper Penny Exists (Wartime Mistake)
6
The Lincoln Cent changed during World War II.
Here’s what happened:
- Copper was needed for the war effort
- The Mint switched pennies to steel coated with zinc
- But a few leftover copper blanks were accidentally used
This mistake created the 1943 Copper Penny
Today, it’s known as the “Holy Grail” of Lincoln cents.
Step-by-Step: How to Identify a Real 1943 Copper Penny
The Magnet Test (FASTEST METHOD)
8
This is the most important first check.
Steel penny: sticks strongly to a magnet
Copper penny: does NOT stick
If it sticks = it’s NOT the rare coin.
Check the Weight
6
Use a precise digital scale:
- Copper version: 3.11 grams
- Steel version: 2.7 grams
Even small differences matter.
Examine the Date Closely
6
Look carefully at “1943”:
Genuine: natural date engraving
Fake: altered from “1948” pennies
This is one of the most common fraud methods.
