See what I did there... Okay, so I've asked the rest, and now... I'll ask the best. Two coin shops said legit 76 Lincoln cent but weight and magnetism make no logical sense. And that leaves everyone curious, both shops offered to buy it, but until I figure this thing out, I'll hang onto it. Both said if I find an answer, let them know. So what say you? 1976 D Lincoln by RGeeez posted Oct 26, 2024 at 1:19 PM 1976 D Lincoln by RGeeez posted Oct 26, 2024 at 1:19 PM 1976 D Lincoln by RGeeez posted Oct 26, 2024 at 1:19 PM 1976 D Lincoln by RGeeez posted Oct 26, 2024 at 1:19 PM
From your photos you can see a grey colored metal showing through the worn areas. This tells us it was plated at least once. Let's assume it is a mint made error. As you said there are three ferromagnetic metals: Nickel, Cobalt and Iron/Steel. Cobalt is immediately ruled out since it has never been used for coinage (to the best of my knowledge). Nickel is also quickly ruled out. No pattern coins were struck at the Denver mint in 1976. The Denver Mint struck 9 different coins for foreign countries in 1976. Seven of these are 75% Copper, 25% Nickel, One is Brass and the last is 55% Copper, 27% Nickel & 18% Zinc. Nickel has to be around 55% pure to be ferromagnetic. Now we are left with steel. Is it possible a 1943 steel Cent was over-struck by 1976 dies? Yes. Mint employees have created unlogical "error" coins in the past, but your coin is copper colored. If they were trying to create an error coin then why would they plate it afterwards? But, even if this was the case, a steel cent weighs 2.70 grams. A copper plating would make it weigh more, but not .56 grams more. So here's my hypothesis: Someone made a magician's coin by plating it in a ferromagnetic metal, let it cool, then afterwards plate it second time in an copper colored metal to hide the telltale silver color.
Simple. The surface has been plated with a ferromagnetic metal. It also looks like there's a metal bezel around the edge. Ferromagnetic means it's attracted to a magnet. Coins are not magnetic.
Possible. Not sure why anyone would do that, other than art for art sake, but if so, they did one beautiful job. Either way, it's such an anomaly I think it's a keeper. I didn't take a decent edge picture but one coming up.
LOL paddyman... If it wasn't, I'd be building bullet proof electric cars and sending rockets to Mars shortly
Easy answer, except gold, silver, bronze and copper electro-plating is not magnetic. But don't take my word for it... Look it up. I used to work in a high end body shop for many years following highschool. I replated a lot of emblems. The materials used in plating in any metals are not magnetic. I have a suspicion of what this coin actually is and why it's magnetic, but I haven't been able to validate my thoughts... Yet. You're plating medium is basically the powder form of what you want it plated in. Iron, nickel, and cobalt are the only exception to the rule and would apply to paddymans original response. But those are silvers or blue to red tints where cobalt is concerned.
It's okay guys, it's okay to say I don't know. Watch, I'll say it... "I seriously don't know". I'll figure it out though. Just thought I might find some expert insite here. And I'm not knocking anyone, I thank you all for your responses. Just the responses are easy answers that don't really apply in reality. I'll probably never really know what this thing is or why it's magnetic. But the main thing we all do agree on is .. it shouldn't be magnetic.... But it is. Sooo... Hmmm...
I explained to you.. it's not magnetic. It's ferromagnetic. That means that it's attracted to a magnet. What part of that don't you understand? It's definitely plated which explains the extra weight.

Ferromagnetic - steel base. That just leaves a question to be answered by a question that doesn't address the question. Not everyone on here doesn't understand large fancy words. I'm pretty educated. So again, not trying to be antagonistic, at all. But since you won't look up your own words... I did so for you, and I am doing so with a smile, in an absolutely non antagonizing way... I've seen many on here lash out at others because they don't accept canned answers... So as professionals, let us all consider what our words we toss around actually depict. "Ferromagnetic" describes a material that exhibits strong magnetic properties, meaning it is strongly attracted to a magnet and can retain its magnetization even after an external magnetic field is removed, essentially allowing it to become a permanent magnet. So please help me to understand here how ferromagnetic plays any role in a copper based item or a copper electroplated item? I'm completely open for alternative theories. So don't get mad because I'm open to further explanation. Just share with me what you are referring to when you cite "ferromagnitism" and how it could even remotely apply here when discussing a copper penny? Perhaps you know something about copper I'm unaware of. In this case, I want to know what you're thinking along these terms. And I am honestly interested in something you may know that I may not know.
YES YES YES... THAT Right There was MY Resolution to THIS Coin! I just told my brother a half hour ago, I think this is a magicians coin!! Boom... There it IS. You da man! The whole ferromagnitism thing lived a short life with me... Made no sense. However... I stated earlier, I think I know what it is, but I need to confirm it. I was unable to find one in a 1976 coin... But I can find them in 60's era coins. However... I think this particular coun weighs more because it's been drilled, metal inserted and repaired. So, okay... I won't be building bullet proof electric cars and doing mars rocket missions anytime soon. But you, my friend... A+ to you because not many know about that kind of magic. I'm going with your explanation. Sure was fun though when I found it. Although, when I saw the date... Nothing made sense... At All...
Magnetic is not the proper term but most of the world uses the term and understands what is being said. Few understand or care about the difference between the two terms. I don't care what folks call it or wish to correct those that use the wrong term. There are more fun things to do.
Yes this is true, copper was needed for the war effort, so they were made of steel... Steel does fall into the category. I'm sure you all might know this, but if not, here's a payback tip for the group and all the replies... I've found several steel cents in a place some might never think to look. Coinstar style machines. Actual coinstar brand machines have have a coin return tray and don't employ magnets. But the non coinstar machines have magnets just below the collection point.... and well, within finger reach. I'll give you three guesses what those magnets catch, and two don't count. If your local machine uses the magnets? Visit periodically. Very much worth the time spent. You'll definitely find more paper clips than rare steel coins... But keep looking. Even a stopped clock is right twice every day. Or who knows? You might find your very own magicians coin...
