The Constantinian age has some of the most interesting coins ever: ... And maybe some of the dullest too :/
If you don't know me too well, I tend to focus mainly on empresses & this year Silver Tetradrachms. I only get get Constantinian and such for my 1 per emperor style collecting.
I can think of that standing for something other than Late Roman Bronze and probably something Mat would actually like, but I don't want to get kicked off the forum...
