Not at all certain since I can't make out any of the legend, but the second portrait looks like Domitian too me. Something like this, maybe: https://www.acsearch.info/search.html?id=1645303
Zumbly, THANK YOU!!!! You've found a similar, but on my other inscription, although it is difficult to read. there is a delta and N. Probably I have another coin !!!!! Where the head is similar to August have the letters:NNΩN
Dear ladies and gentlemen, I will be very glad and happy if you could help me with this coin. Who - ever heard of the Emperor or 2 emperors on my coin?
