Yes, that helps some - but only to a point, at least for me.
I'd say
IEPA CYN-K(lambda)HTON (or maybe substitute sigma for the N) is clear apart form that very last letter.
On the rev, starting just to the left of the point of the
bust, seems to be
(theta)EAN P(omega) KPA....
I'm tempted to interpret that as naming the goddess
Roma and the start of the name of a magistrate (Cra...). Maybe the Cratippos listed in Münsterberg for
Pergamum? That is going out on a limb, so I
hope someone can confirm or correct me on that speculation.
