Here is some information on your damaged Copper Plated Zinc Cent http://www.error-ref.com/?s=Zinc+rot
Clearly you are if you are thinking that a 1988 cent should weigh 3.1 grams. Also, @paddyman98 and @Dave363 are correct.
Well you have a real gem if that coin weighs 3.1 to the best of my knowledge they weigh 2.5 I would check my scale.JMO Dave

Certainly didn't want to hurt any feelings...but this is a bit dumb. Perhaps I should get back to work now
Thanks for being kind. And yes they are correct, but stay and participate, all of us are learning new things every day. Jim
