This 1958 D penny caught my eye while searching through old pennies. Thought it was very shiny 1943 steelie when i first caught glimse. Never seen one like this before. Picture dont do justice for the actual color if it. I placed it between another 1958 penny and a 1943 steel cent for comparison. Can anyone tell me whats up with it please.
Oh and to add (probably the most important part) I did not weigh the coin. Will not be able to weigh it until tomorrow at work. I will post it then. And dropping it onto table it sounds like a normal bronze penny.
It was plated after it left the mint. This was a common science experiment done in HS Chemistry classes back in the day. It is not a mint error If you the way it looks, here is how to make more: https://www.sciencecompany.com/Turn-Copper-Pennies-Into-Silver-and-Gold-Pennies.aspx
I disagree. Because that looks exactly like the one I have and if you put a magnet to it it doesn't jump to it drastically but its definitely being pulled to it. And I'm pretty sure that high-school experiment didn't figure out a way to make copper magnetic. I've been digging deep into this and we most likely have a 1958 penny that was struck on a wrong planchet. America makes a lot of other countries coins for them. Mine also an offset outer edge.
That's too bad. The correct answer has been given on this forum numerous times. Send it to a major coin attribution/grading company and get back to us. BTW.. We need pictures of your coin or it doesn't exist Welcome to CoinTalk
Of course the copper isn't magnetic, but what about the plating? If it were nickel plated or chrome plated using a nickel strike, it would be attracted to magnet. You're correct that the US made coins for other countries, but In your research, did you find a planchet that matches the size and weight of your coin? That was used around 1958? At the correct mint? Here's something to help you dig deeper. See what you can find https://minterrornews.com/news-5-13-03-foreigners_in_the_mint.html
First, welcome to the neighborhood! Don't be so quick to disagree. Some of us have been collecting coins for 50-60 years, and with the advent of the internet, we've seen countless examples like this. Most of them originated as science projects. So, until you can submit yours to one of the major grading services and have it attributed as such, we'll have to follow our gut.
