Looks like a drachm from Apollonia. On the reverse I read AΠΟΛ - ΔAMO - ?ON - TO(Σ?), so perhaps magistrate ΔAMOΦΩNTOΣ? However, that name is written with an omega in the middle and not an omikron. On the obverse I read ?IMHN, so perhaps magistrate TIMHN? I can't really make up the first letter.
Yes, that is exactly the two magistrates I mentioned, TIMHN and ΔAMOΦΩNTOΣ. But it seems on @galba68 his coin there are different letters used. For example, the first letter of TIMHN and on the reverse the name ΔAMOΦΩNTOΣ is written with an omikron rather than an omega. I suspect archaic local variants are used, or perhaps illyrian onomastics, not that uncommon in Thrace and Illyria (atleast I remember this from inscriptions when I was studying ancient Greek history, culture & the arts).
An interesting coin. My inexpert guess is that it is a contemporary imitation/variant, as Pavlos suggests. Whenever I have an Illyria question, I go to this site, where there is an abundance of information: https://asklapiadas.ancients.info/ The menu is on the left and pretty easy to negotiate. There is a fake/imitation section: https://asklapiadas.ancients.info/10bFakePyoDta.html
