Actually the guys who made the coins, from imperial celators to the slaves wielding the mallet might have been decent human beings. Of course we associate the rulers on the coins with the coins themselves but I really wonder whether rulers took that much of an interest in the fabrication of their coinage. I can, in all good conscience collect ancient coins because doing so does not in anyway endorse the people on them. I collect a lot of things, mostly connected to the study of history, that I used in teaching history. There were areas and objects and subjects I stayed away from, mostly from more recent history, because I feared my students might think I admired them and supported their activities. I think I am OK with ancient material as no one is likely to support ravaging Gallia or promoting Mithraism or thanking Victoria for driving back the barbarians from the gates.
I'll look forward to reading your pick. It's certainly possible to find equally ruthless leaders from history.
That is one of the nicest strikes of this emperor I have ever seen. I am guessing the first N of his name is not wear but a filled die.
