You’ve probably heard the stories. Someone finds a dusty jar in their grandfather’s attic, tips it out, and—boom—there it is. A penny worth more than a luxury condo. It sounds like a total urban legend, but in the world of coin collecting, it’s actually happened.
Honestly, most people think the "holy grail" of pennies is just any old coin from the 1800s. Or maybe that shiny 1943 steel penny they found in a checkout lane. Sadly, those steel ones are usually worth about twenty cents. If you want to talk about the most valuable penny in the world, you have to look for the mistakes. The stuff the U.S. Mint never meant for you to see.
The $1.7 Million Mistake: 1943-D Bronze Lincoln Cent
When collectors talk about the big one, they are almost always talking about the 1943-D Bronze Lincoln Cent. It is, by most expert accounts, the single most valuable penny in the world.

Back in 1943, the U.S. was deep into World War II. Copper was needed for shell casings and radio wire, so the Mint switched to making pennies out of zinc-coated steel. They looked like silver dimes at first glance. But, as it turns out, a few bronze planchets (the blank metal disks) from 1942 were left stuck in the hopper bins.
When the machines started cranking for 1943, those stray copper blanks got stamped with the new date. Only one was ever confirmed from the Denver Mint. In 2010, that lone survivor sold for a staggering $1.7 million.
Think about that. A piece of metal that was supposed to buy a stick of gum ended up costing as much as a private island.
Why the 1943-D specifically?
There are about 20 of these copper-colored "errors" known from the Philadelphia and San Francisco mints. They’re rare, sure. But the Denver one? It’s unique. It’s the only one known to exist from that specific facility. That kind of "one-of-one" status drives billionaires into a bidding frenzy.
The New King? The 2025 "Omega" Penny
Now, if we are being technical about the current market, things just got weird in late 2025. You see, the U.S. government officially stopped making pennies for circulation in November 2025. It was a huge deal. No more zinc, no more "worthless" cents clogging up your car's cup holder.
To mark the end of an era, the Mint held a special auction in December 2025 through Stack’s Bowers Galleries. They sold the very last pennies ever struck.
One specific set—Set #232—contained the final three pennies ever made: a standard 2025 penny, a Denver-minted 2025-D, and a special 24-karat gold version. All of them featured a tiny Greek letter Omega (Ω). That set sold for $800,000. While it didn't beat the $1.7 million record of the 1943 bronze cent, it proved that the "last" penny is just as seductive to collectors as the "mistake" penny.
Other Contenders for the Crown
It isn't just the 1943 bronze cent or the 2025 Omega set making waves. There's a whole tier of "mega-pennies" that trade hands for enough money to retire on.
- 1944 Steel Penny: This is the mirror image of the 1943 error. In 1944, the Mint went back to copper, but a few steel blanks from the previous year got caught in the machines. A high-grade 1944-D steel penny can easily fetch over $1 million.
- 1793 Chain Cent: This is a monster for history buffs. It was the first penny ever officially struck by the U.S. Mint. It doesn't have Lincoln on it; it features a wild-haired Lady Liberty and a chain on the back. Because the chain was seen as a symbol of slavery, the design was scrapped almost immediately. High-grade versions have sold for $1.5 million or more.
- 1958 Doubled Die Obverse: This one is a "sleeper." Most people walk right past it. But if you find a 1958 penny where the letters in "LIBERTY" and the date look like they were printed twice (a ghosting effect), you're looking at a $300,000 coin. Only three are known to exist.
How to Tell if You Actually Found One
Before you start calling auction houses, you've gotta be realistic. Most "copper" 1943 pennies are fakes. People in the 50s used to copper-plate the steel ones just to mess with their friends.
The Magnet Test
This is the simplest thing you can do. Grab a kitchen magnet. If your 1943 penny sticks to it, it's steel. Even if it looks brown and copper-colored, it's just a plated fake. A real 1943 bronze penny will not stick to a magnet.
The Weight Test
If it passes the magnet test, get a digital scale that measures in grams.
- A real 1943 bronze penny weighs 3.11 grams.
- A fake plated steel penny weighs about 2.7 grams.
If you've got a 3.11-gram penny dated 1943 that doesn't stick to a magnet, don't clean it. Seriously. Don't touch it with soap, don't scrub it with a toothbrush. You’ll strip away the "patina" and potentially lose $100,000 in value in ten seconds.
What to Do Next
If you actually think you’re holding the most valuable penny in the world, your first step isn’t eBay. It’s authentication.
You need to send the coin to a third-party grading service like PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Company). They are the ultimate word. They’ll put it in a sonically sealed plastic "slab" with a grade on it. Without that slab, no serious collector will touch it because the risk of a high-end counterfeit is just too high.

Check the dates in your change jars. Specifically, look for 1943 pennies that look like copper, 1944 pennies that look like silver, and 1969-S pennies with blurry, doubled lettering. You probably won't find the million-dollar winner, but even the "smaller" errors can pay for a very nice vacation.
The era of the penny is officially over as of 2026, which means these little copper relics are only going to get rarer. Keep your eyes peeled. The "most valuable" one might still be sitting in a coffee can in someone's basement, just waiting to be noticed.
