Hello, I am new to this forum so I'm still learning. I posted about a possible penny struck on a dime planchet, but I put it in the Q&A forum. Can anyone go to that forum and take a look? Thanks.

Those are his pictures from his other thread.
Looks to me it is an acid damaged coin, the copper coating is most likely warn away revealing the zinc interior. Sorry.
Thanks for the info. That's kind of a bummer. lol
Hi and Welcome To School! I say school because you'll not only be taught about coins but in many other areas. Such as, in ethics, manners and in business. Your first thread is interesting. To me, it appears as you are interested in the error/variety game? I too, am involved in these two areas. It makes it twice as fun and twice the chance of picking out a premium coin. Instead of the normal value, one can really make a profit if you care to take the time to look? You came to the right place to ask questions. This Forum is well knowledgeable as you can see by the previous posts. Remember, don't be a stranger here and post often. Also, the most important thing is to have FUN! Once again, Welcome to our Forum. -joey

--- If it should happen I die and leave this world and you want to remember me. Please only remember my opening Sig Line.It is a bummer, but we all started where you are at one point. When wondering if you found the next great error coin, it's probably best to ask yourself first "What post mint things could have happened to this coin to cause what I'm seeing?" There are far more ways for a coin to be damaged after it leaves the mint than there are in the mint. Especially when you find one that looks as rough as the one you have...think "damage" before you think "error."
As Joey said, if you enjoy coins and stick around...you'll learn a ton!
what acid would attack the copper but not the zinc?
I've put them in vinegar and little imperfections in the copper allows the vinegar to bubble the zinc out of the interior and leave a copper shell.
but, what acid would attack the copper but not the zinc?
anyway, it looks like Lincoln, the date, the devices and the rim are worn, so I'm guessing the copper plating is simply worn off.
Like I said, I'm new to this but there are definitely some weird things about this penny. It's half the thickness of the other 1994-D penny I have sitting next to it, and it even varies in thickness throughout. It is also smaller in diameter than the other penny. Just kind of weird to me. I can completely accept that the penny has had the copper plating taken off with acid, but would it wear that much without the copper? Zinc is even harder than the copper on the outside of it, correct?
Nitric acid would dissolve copper and leave the zinc in tact.
Zinc is lighter than copper.
I think they are in the same magnitude of hardness.
I saw on a site a couple of people discussing removing the copper and keeping the zinc with a couple of different chemicals. one was dilute sulfuric acid.
due to the significantly reduced diameter, a chemical attack may be the better answer than my "wear" answer.
Definitely a cool find. I'm not sure what would have caused the difference in size. I do know sulfuric would have destroyed the zinc along with the copper.

The idea included removing it once the copper was gone. This may also explain why detail and diameter was lost.
Actually, the reduced diameter - with the rims still appearing intact - makes me wonder. I totally agree with the acid theory... except when it comes to those rims... I still believe it is PMD... In hand, perhaps it is more explainable... or larger magnification of the the rims, side by side... Cheers, RickO
weathered penny or a penny that has been in the ground just IMHO
