Quick Hunt: That Old “Steelie” Might Not Be Steel At All! Uncover the Truth About the Million-Dollar Penny.
At Coin Collector’s Corner, we delve into the most legendary coins in history. The 1943 penny is famous, and many families have the silver-colored “steel cents” like those in the photo, saved as wartime curiosities. But the real treasure, and the subject of a global hunt, isn’t the common steel penny. It’s the coin that shouldn’t exist: the 1943 Copper Penny, a legendary error worth anywhere from $10,000 to over $1,000,000!
This guide will clear up the confusion and show you how to identify if you have one of the most valuable coins in the world.

The “Silver” Steel Penny vs. The Million-Dollar Copper Error
First, let’s clear up a common misunderstanding. The coins in the image, often called “silver pennies,” are actually zinc-coated steel.
- The Common 1943 Steel Cent: In 1943, during the height of World War II, copper was a critical material for the war effort. To conserve it, the U.S. Mint switched to making pennies from steel with a thin zinc coating. Over a billion were made. Today, they are very common and usually worth between 25 cents and a few dollars.
- The Legendary 1943 Copper Cent: The million-dollar error occurred when a few leftover bronze/copper planchets from 1942 were accidentally fed into the coining presses. Struck with the 1943 date, these copper pennies were mistakes that never should have left the mint. Fewer than 25 are known to exist from all three mints combined, making them exceedingly rare.
The Path to $1,000,000: The 1943 Copper Penny’s Value
The value of a genuine 1943 copper penny is immense and depends on its condition and mint mark.
- $10,000 – $100,000: This range is for genuine but heavily circulated, damaged, or corroded examples. Even in poor shape, it’s a five-figure coin.
- $200,000 – $500,000: This is the typical auction range for authenticated, problem-free examples from the Philadelphia (no mint mark) or San Francisco (“S” mint mark) Mints.
- $1,000,000+: The absolute peak of the market. This valuation belongs to the king of all 1943 cents: the 1943-D Bronze Cent. Only one single example is known to exist from the Denver mint. It last sold for $1.7 million, and today, experts estimate its value could exceed $2 million. A new discovery of a pristine Philadelphia example could also approach the million-dollar mark.
How to Tell if You Have the Million-Dollar Error
You don’t need to be an expert to perform the most critical test.
- Step 1: The Magnet Test (The ONLY Test You Need!) This is the simplest and most definitive test.
- The common STEEL penny is MAGNETIC.
- The ultra-rare COPPER penny is NOT MAGNETIC. If you have a 1943 penny and a simple refrigerator magnet sticks to it, you have a common steel cent. If the magnet does not stick, you may have just found a fortune.
- Step 2: Check the Color and Date
- A genuine copper cent will have the distinct reddish-brown hue of a normal penny, not the silver-gray color of a steelie.
- Examine the date “1943” closely with a magnifier. Many fakes are created by altering the “8” on a 1948 penny. Look for unusual marks or tooling around the “3”.
BEWARE OF FAKES!
Because of its fame, the 1943 copper cent is one of the most counterfeited coins. Besides altered dates, a common trick is to plate a normal steel cent with copper. The magnet test will instantly expose this fake, as the coin will still be magnetic.
Maximize Value: If Your Penny Isn’t Magnetic…
If you have a 1943 penny that is not magnetic, you must proceed with extreme care.
- DO NOT CLEAN IT:
Cleaning will destroy the coin’s surface and a significant portion of its value.
- Handle by the Edges: Protect it from scratches, dings, or fingerprints.
- Get it Authenticated:
This is not optional. A coin of this caliber MUST be certified by a leading third-party grading service like PCGS or NGC. Their authentication is the only way to prove it’s real and unlock its immense value.
- Contact a Major Auction House: A genuine 1943 copper cent is a world-class rarity. The best way to sell it is through a major auction house like Heritage Auctions or Stack’s Bowers, which can market it to the world’s most serious collectors.
