Imagine finding a simple penny in your pocket that could be worth over $500,000 
Sounds impossible? One rare 1943 Copper Lincoln Cent sold for $504,000, and experts believe a few may still be hidden in everyday change.

During World War II, the U.S. Mint stopped using copper for pennies to save metal for the war. But a tiny batch of copper blanks accidentally slipped into production — creating one of the most valuable coin errors in history.

Let’s break it down step by step so you can easily check your own coins 

 What Makes the 1943 Copper Penny So Valuable?

This coin is considered the Holy Grail of U.S. pennies for three main reasons:

 Extremely rare (fewer than 20 confirmed worldwide)
 Historical WWII minting mistake
 Huge demand from collectors and museums

Some examples are even displayed in the Smithsonian 

 Step-by-Step Guide: How to Identify a Real 1943 Copper Penny

Follow these simple tests to see if you’ve found a jackpot coin 

 1. Magnet Test (Fastest Check)

• Real copper penny:  Will NOT stick to a magnet
• Common steel penny:  Strongly magnetic

 This is the easiest way to eliminate fake finds.

 2. Weight Test

• Genuine copper: 3.11 grams
• Steel penny: about 2.7 grams

 Use a jewelry scale for accurate results.

 3. Visual Color Check

Look closely at the coin:

• Real copper = reddish-brown tone
• Steel penny = silver or gray color

Also check the edge — real copper shows solid copper color.

 4. Sound Test

Drop the coin gently on a hard surface:

• Copper = dull, soft sound
• Steel = sharp, ringing sound

 5. Mintmark Inspection

Check below the date:

• No mintmark → Philadelphia
• “D” → Denver
• “S” → San Francisco

All mintmarks exist for rare copper versions.
