Guess The Emperor Revised Again

That's not really a clue - haven't kept track whom you consider good or bad.

But that is not preventing me from guessing:

Severus Alexander?

Will have to remember that, here not the best portrait either bad I hope he can be recognised:

Later than Hadrian and also a shorter reign.

Getting close, as another hint: he died not 'by the sword'.

Yes, it's him. Btw, BMC Pontus is unfortunately not available as download (not even the plates on Snigle), but as google-book. Have some copies of BMC but doubt Pontus is amongst them - if you can't find a reference for the Severus otherwise, you might have to ask Varbanov.
But here is the coin:




AE 25 from Caesarea (Samaria) of Hostilian as Caesar - BMC#191+

Obverse: HOSTILIA[NO QVIN]TO CAES around radiate bust right, wearing paludamentum and cuirass
Reverse: [COL] PFAVFC CAES METROP around bust of Tyche wearing turreted crown

Here one, so that whoever is online can have a guess:

No - different realm.
