I just received two coins in the mail that I purchased from JW. They are really nice coins for the money, I think. He originally offered me two Constantine I posthumous coins because I have been looking around for them for a reasonable price. I purchased one that he offered, as you will see and another.

Constantine I AE4 - RIC VIII 48 - Nicomedia

This is a Tetricus II. The odd thing is that it changed to a dark color during transit to here. I noticed that with some of the other coins I received as well but it never happened to any modern coins I ordered. Has this happened to anyone else?
I will be giving this coin a ID soon.
