Hello... I wonder (being a newbie) what exactly it is about this coin that causes you to think that it may have been minted onto the wrong (a dime, presumably?) planchet? Thank you in advance.
What is the weight, the thickness and diameter ? A dime planchet is much smaller, and a different color from different metals. So the outer devices wouldn't even be able to be printed on it unless it was super duper thin a nickel planchet is over 2mm too wide to fit into a cent collar a quarter is way too large to fit in a cent collar back to the question of (a) why you think it's on a wrong planchet; (b) what planchet do you think it's from and why; (c) how would it possible get minted?
Oh! @Clawcoins - I went to read and learn about wrong planchet errors. I read an article indicating that a 'penny' could be struck onto a dime planchet. I could link to that article but I don't want to give a link to an incorrect article in case others, like me, go learning information that isn't the truth. So, since you are sure a cent can't be struck onto a dime planchet in the normal minting process, then I am happy to learn that and I won't rely on THAT organization's information again in the future.
you can stick a dime planchet in a cent machine because it is slightly smaller and will fit - 17.9mm vs 19mm diameter and 1.35 thick vs 1.52. https://www.usmint.gov/learn/coin-and-medal-programs/coin-specifications But you'll have certain indications of thickness, visual appearance, etc which are not evident at all on his cent. Thus my unanswered questions .. reread them. If someone wants to ignore certain comparisons then just hold a dime and cent next to each other and look at the color, thickness, width. Then think of what happens if a dime is smashed down to make it as wide as a cent. The cent image though, the die is not going to make itself smaller so that everything shows perfectly on a much smaller dime so it smooshes it a bit thinner, right?. Look at his cent. What is the composition? is it copper or more of the silvery dime composition (which is mostly copper but more nickel in it? Does it look like an incomplete cent due to the dime planchet? and his penny is a 1984 .. that's a zincoln ... it looks like one too with bad environmental damage.
I took your directive @Clawcoins , to reread your questions. The first two were the questions I posed (pretty much). As to your third question, an article I read described that the big vats or containers that held the planchets were not dedicated to a particular coin and that it could happen that, for instance, a dime planchet or more might remain in a bin next intended to hold planchets to make cent coins and when the cent planchets were introduced to it, those dime planchets would become mixed in and then fed into the stream of cent planchets which were struck. I am not defending the OPs suggestion that his coin may be a wrong planchet error. I, too, am asking him why he believes it might be. And I ask, not to help teach him anything for I am ignorant about almost all of this. I ask hoping to learn something for myself. I will sit back and just read as I have nothing else to offer.
