1943 Copper Lincoln Cent

In 1985, The New York Times reported the sale of a rare wartime penny for $20,350, calling it one of only about a dozen known survivors of a strange mint mistake. That coin was a 1943 Copper Lincoln Cent, a penny that was never supposed to exist. The U.S. Mint meant for every 1943 cent to be struck on zinc-coated steel to save copper for World War II, but a small number were accidentally struck on leftover bronze blanks from 1942, and today those coins can sell for six figures or more.

If you think you might have one, here's the short answer: a real 1943 copper cent is nonmagnetic, weighs about 3.11 grams, and is one of the rarest coins in American history. Fewer than two dozen are known to exist across all three mints that struck cents that year. This guide walks through how the error happened, how many exist, what drives the price, and how to check a coin before you get your hopes up.

What Is a 1943 Copper Lincoln Cent?

A 1943 Copper Lincoln Cent is a Lincoln penny struck by accident on a bronze planchet left over from 1942, instead of the zinc-coated steel the Mint had switched to that year. It is nonmagnetic, weighs close to 3.11 grams, and is one of the most famous error coins in U.S. history.

Collectors and grading services often call it a "bronze" cent rather than a copper cent, because the alloy is 95% copper mixed with 5% tin and zinc. That distinction matters to numismatists, but to everyone else it's still "the copper penny" that turned a wartime metal shortage into one of the biggest stories in coin collecting.

How Did the 1943 Copper Lincoln Cent Happen?

The 1943 copper cent exists because a handful of bronze planchets from 1942 got mixed in with the new steel stock when the Mint switched metals for wartime production. It was a mistake, not a special issue or a planned rarity.

The U.S. Mint needed copper for shell casings, wire, and other war material in 1943, so it moved cent production to zinc-coated steel for the year. Steel presses ran at all three mints, in Philadelphia, Denver, and San Francisco. Somewhere along the line, leftover bronze blanks from the prior year's production sat in a bin or hopper and got fed through the coining press right along with the new steel planchets.

How Many 1943 Copper Pennies Exist?

Roughly 20 examples of the 1943 copper Lincoln cent are known across all three mints, and that number has barely moved in decades. PCGS puts the total known population at about 20 coins, and most of those trace back to the Philadelphia mint.

The rarity is not spread evenly. Some mints produced far fewer surviving examples than others, which is a big part of why grade and mint location move the price so much.

That single known 1943-D bronze cent deserves its own mention. One coin, one mint, one shot at ownership for whoever holds it. If you want the fuller picture of how the more common steel version compares mint by mint, 1943 S steel penny grading and value breaks down that side of the story.

How Much Is a 1943 Copper Lincoln Cent Worth?

A genuine 1943 copper Lincoln cent is generally worth six figures or more, with public auction results ranging from about $204,000 to over $500,000 depending on the mint and grade. This is not a coin priced off a chart the way a common bullion coin is priced off spot.

Recorded sales tell the story better than any estimate. A 1943 bronze cent brought $204,000 at a Heritage auction. Another example, graded AU58, sold for $218,500 according to PCGS auction records. A different piece brought $329,000 through Legend Rare Coin Auctions. And the 1943-S bronze cent from the well known Simpson Collection realized $504,000 at Heritage, a price that reflects both the coin's extreme rarity and its documented ownership history, what collectors call provenance, meaning the record of who has owned a coin and when.

That's the key thing to understand about this coin. Melt value is irrelevant here. A steel 1943 cent or a common wheat penny might be worth a few cents to a dollar or two, but the bronze error cent is priced purely on rarity, condition, and pedigree.

How Can You Tell If Your 1943 Penny Is Real Copper?

Check two things first: does a magnet pull the coin, and does it weigh about 3.11 grams on a gram scale. If the coin sticks to a magnet or weighs closer to 2.70 grams, it's a normal steel cent, not the rare bronze error.

Steel 1943 cents are magnetic and weigh less. Bronze cents are nonmagnetic and heavier. That's the starting checklist, but it is only a starting point, because fakes exist and they are good enough to fool a magnet test.

If a coin passes the weight and magnet checks, that's encouraging, but it is not the final word. This is one of the most copied coins in American numismatics, so a trip to a grading service is worth the time and the fee before you assume you're holding a life-changing find.

What Are the Biggest Myths About the 1943 Copper Cent?

The biggest myth is that a nonmagnetic, copper-colored 1943 penny is automatically the real thing, when in fact counterfeits are common and only professional review can sort out the real coin from a clever fake. A few other misunderstandings show up again and again in online searches and family stories about an old jar of pennies.

That last point trips up a lot of people who read one article and treat the number as fixed. Numismatic research keeps evolving, and even major references list slightly different totals depending on when they were last updated.

How Does the 1943 Copper Cent Compare to the 1943 Steel Cent?

The steel cent is common and cheap, while the copper cent is one of the rarest coins in the country, and the difference comes down to a wartime metal switch that almost every 1943 penny followed correctly. Over a billion steel cents were struck that year. Only a small handful of bronze cents slipped through.

Most 1943 pennies people find in old collections, jars, or estate boxes are the steel version, and that's not a bad thing, it's still a piece of wartime history. If you want the full picture on grading and pricing that common steel cent, the 1943 Lincoln steel cent wartime switch guide covers what those coins are actually worth today.

Why Is This Coin So Famous Among Collectors?

The 1943 copper cent is famous because it was born from a wartime mistake, not a planned rarity, and that accidental story has stuck with collectors for eight decades. It's the coin that proves even the most controlled minting process can slip up, and that a slip-up can become one of the most searched-for coins in the hobby.

The 1943-S bronze cent from the Simpson Collection is a good example of how far the story reaches. That single coin realized $504,000 at Heritage, a number that reflects both its rarity and the reputation of the collection it came from. Elite ownership history can add real weight to an already extreme rarity, which is part of why coin collectors track pedigree as closely as grade.

If you have coins from this era and want a straightforward read on what you're holding, weigh it, check it with a magnet, and if it clears both tests, get it in front of a professional before making any decisions about buying or selling it.
