Help With Seleucid Kingdom - Antiochus Identification

[-monolith-]

Is this coin Antiochus II or Antiochus III or someone else? It was sold at two different auctions as Antiochus III, however I can't seem to find a portrait match. I have several Antiochus II coins and this one definitely looks different.

There is no way to tell without the controls visible. Options for right facing are Tyche, Antiochus III, or Apollo. If it's Apollo there are hundreds of dies to choose from.

I'm not much help either with these.  But here are three of mine - all Antiochos II, or so I think.  The portraits do seem to have some variation, though the OP does look further "off" than the others I've seen (the top two of these have countermarked reverses - anchor/over/anchor for some reason):

..here's my bronzes of Antiochus l (Soter)and ll (Theos) , 1st featuring Athena ob. with reverse of the Dioscuri twins hat with club under and the 2nd Apollo obverse with with a kithara reverse

Judging from my experience: the outlines of the head and face, in my opinion, suit Antiochus III best. But as @Celator wrote, it certainly hard to said without additional controls
