The obverse has luster and looks normal but the reverse is matte with no shine. What would cause one side of a coin to have a matte finish with no shine at all? When looking at the edge it still looks like it has a layer over the copper. I also have an 84 D with the same issue.
Thanks everyone for the help. It doesn't look like there is any damage at all to the devices so I didn't initially think environmental damage but weird things happen to the finishes. That's the second one I have found. I appreciate the help.
