I need your expert opinion on this 2006 penny.
It has what looks like a partially plated planchet only on the bottom right quadrant of the reverse.
Is this uncommon?
Thanks,
Agree with the previous analyses. The copperish tinge around the T in Cent points to post-Mint discolorization instead of insufficient plating. It wouldn't be there if the zinc core was fully exposed.
I should have noted that the non-copper area is lower and it slopes up to the copper in the light colored transition area. The edge and front are all shiny copper. Not a stain - you can see and feel the difference.
