Yay, thanks. I looked it up in my brand new set of the RIC.
I got these three as part of a really wierd lot of about 110 coins I bought last week which had Greek, Roman and Byzantine in it. Whole lot was $100. Also found two Claudius "Minerva with shield) As, another large Augustus AE, and one empress I can't figure out - hair has a bun down by the neck and can only make out a few letters but they don't make sense. I'll puzzle over this for a little longer before posting it up.
