One on the left is a Roman Denarius of Faustina I, common type and in that shape, maybe $60. It's nice and has a nice tone. Right coin, no clue. Could be a fantasy piece.
Thank you, always find it tricky to figure out who's depicted on Roman coins. on the right: That's interesting. Be interesting to see what other people think.
I think Mat has it about right! The 'fantasy piece' or whatever looks 'nice' but I don't think it has much value---maybe $10.00 ???? The 'common' DIVA denarius is in terrific shape, so you may be able to get a little more than Mat said from the right buyer.
