I need a opinion on a coin I received from the bank. I have asked others who say they are pro but dismiss it. I have a 2021 penny that's silver in appearance but is magnetic. I have had people say it's coated with something but it weighs what a regular penny of that year should. I have even tried making a mark in it to see if it is coated but it isn't it's a real penny and being as I got it from the bank I don't believe it to be coated cause it would weigh more than it should
