elbarto801 New Member United States 9 Posts	Posted 05/29/2024 10:03 am I have had this penny for some time now. I have never been able to understand what it actually is. When I first found it, I thought it was fake, but then I thought, who would make a fake penny? I set it aside to investigate one day....and that day is today. The color is different. I guess pennies could be this shade/color of copper, I just have not seen one like it. The pictures don't really show the true color so that is hard to show all of you. I have researched foreign planchets, and have not found a match. The circumference matches a normal penny It is thinner than a normal penny. I don't have a way to officially measure it, but it is visually thinner. I posted a pic to try and show that. The 1976 penny is the top one. It weighs 2.2 grams instead of the expected 3.1 grams The minting strike appears to be normal. To me anyway. So I thought I would post it here for some more educated opinions. Thanks.

Chlorine is reactive, but not really "corrosive" in the same sense as acids. It will very slowly react with copper and copper alloys, especially if the pH is neutral or alkaline, but such corrosion tends to be uneven, causing pitting rather than an even spread like we see with acid-dipped coins. The rippled surface seen on this coin is typically caused by two things: acid corrosion, or directed intense heat eg. a blowtorch. Rippling plus reduced mass is a clear indicator of acid damage. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
