I found this 2003 D
LMC with what appears to be an incomplete plated planchet. I do not believe this was chemically altered as there are no flow lines, just a fading of the plating. It was well struck and the zinc shows through as a dull gray with no signs of copper anywhere in the crevices of any of the devises. This cent weighs 2.51 gms. Could this have happened during the annealing process?
