Hello everyone, Still being fairly new to all of this, I've been having a blast slowly going through all my change. And learning about coins. Usually, I can find the info I need for any questions on this site, but I can't seem to find any information on this nickel. Could anybody explain exactly what had happened here? It weighs 4.80 if that helps at all. Thanks in advance- Mike.
Thanks for answer. It's been driving me crazy. Could you please explain how you're able to tell? Is it because of whatever the green stuff is on it?
Nickel sulfate or nitrate in crystalline structure. blue to green , https://www.amazon.com/Nickel-Sulfate-Hexahydrate-99-9-500g/dp/B00OU0WCGQ ( for color comparison) If you are allergic to nickel plating, it is an allergic response to these chemicals.
