I got this one at work. It appears to either be plated or zinc/sodium hydroxideed but my local coin dealer thinks it's an error. What do you think?
If the color actually is not copper there is a possibility it could be an unplated planchet. I do not know how much the plating weighs but, if it is relatively close but under 2.5 grams then it could be worth sending to a grading service for authentication. I've weighed countless post 1982 cents and they were mostly 2.56 - 2.57 grams with some that were .01 or .02 less than that.
