Need help with the coin below. it is 27mm x 25mm and 14.0g. with some damage. I think it may be a silver Ptolemaic tetradrachm, but I could not find an exact match on-line. Any detailed information about its attribution, age, ruler, authenticity, rarity, etc. would be greatly appreciated.
Not sure about the value. Obviously Zurqieh's is in excellent shape. My assumption is that the date (EΣ), in combination with other devices, from this mint, is rare - I am spotting some Antiochos VIII tets with similar reverses, but different SE dates, for a good deal cheaper. Sorry - not my area.
