as the control marks at the left edge of the reverse
are obliterated it's going to be hard to nail this one down specifically but it bears a more than passing resemblance to some entries in SNGIsrael (Spaer) of Antiochos III. #561-2 from Antioch
and/or #786-91 from Ecbatana.
perhaps the find location of this coin can be determined which would help
distinguish the type
given that the identifying marks that would pin it down better are apparently corroded and pitted away.
suffice it to say there are a whole slew of Antiochos III bronzes of similar size and weight with these basic design features. don't feel bad thought - several of the pieces in Spaer attributed to Ecbatana have the control marks worn away. probably worth a look at Spaer or CSE
or SC (v1) if you want to really nail it by comparing detailed portrait style
, etc. ptolemy
