One of my favorite and most rare MSCs is Seleucis I: His grand son was known as great and had some great MSCs:
I got this one misattributed as Alexander I think by either Zeus or Ares in one of their first auctions. I was blown away by the quality of the portrait! These early Hellenistic die engravers were masters of their art
Quite an oversight by the auction house considering that the reverse of the coin clearly reads: ΣΕΛEYKOY, and there is a Seleukid anchor in the field. I have a couple coins of the patriarch of the Seleukid Empire, but they have yet to be photographed, so here's one of his grandson... SELEUKID KINGS of SYRIA. Antiochos II Theos. (261-246 BC). Æ. (16mm, 4.32g). Sardes mint. Obverse: Laureate head of Apollo right. Reverse: ΒΑΣΙΛΕΩΣ ΑΝΤΙΟΧΟΥ; tripod; monograms to outer left and right; anchor below.
