Hi. This silver Tet weighs 15.04 g.I could read Alexandroy and Basileos to each side of the reverse which shows an eagle. There are many monograms as well, but I couldn't match the face on the obverse with any known Alexander, whether Macedonian or Seleucid or Judean. Please post your views. Thanks..
Should be Seleucid I think, but the coin looks not genuine, I do not know this type. Looks a bit like my ever bought Tyrian shekel fake...
Your coin appears to be of Alexander I Balas. The date on reverse ZΞP (167) or EΞP (165) in the Seleukid era equates to 146/5 BC or 144/3 respectively. The OP photo is very "noisy". I am not an expert on Seleukid coins and would not want to comment on authenticity one way or the other based upon it. The monogram below the date does not match any of the monograms I could find on tetradrachms of Balas in a quick search online and in BMC.
