This one weighs 2.63g and I just want to hear from the experts on their opinions. I just found the color different from the regular zincolns so I put it away and just showing it now.

For a Copper plated Zinc cent, the weight is normally 2.5 grams. The weight for a Copper planchet cent is normally 3.1 grams. The one you have is Copper plated over a Zinc planchet.

@vr28, sometimes the copper plating is exposed to an environment or chemical which changes the color. I think that perhaps that is what happened with this one.

Appreciate all your inputs. I just found the color a bit odd and since the weight is 2.63 g. I know the weight tolerance for copper cent is -/+ .13 and for zinc cent is -/+ .10 thus it made me post and inquire about it. It also reminded me on the color of the 1976 LMC I found&

The color of your 1976 P LMC is from it toning in circulation. It can be caused by a chemical reaction.

Thank you EandV. I've seen zincolns having the same toning as well but the weight is within normal. I only asked because it weighs 2.63g and I was just wondering and asked what is the average mass of a solid copper penny in which we all know is 2.63g.

Have you made sure your scale is accurate?
