The Coin of a Murdered Seleucid King
This extremely rare tetradrachm coin is one of only 14 known examples and is worth about $25,000. It was minted in Seleucia Pieria (map) circa 147/6 BC under the rule of Alexander I Balas, King of Syria (c. 152-145 BC). The obverse side shows the laureate head of Zeus and the reverse has the inscription ΒΑΣΙΛΕΩΣ ΑΛΕΞΑΝΔΡΟΥ, a thunderbolt, ϚΞΡ (= year 166) and a monogram above; below, two more monograms; all within an elaborate laurel wreath with ties.
The head of Zeus, of an archaistic style that harks back to the early 5th century BC, was deliberately chosen by Alexander Balas’ moneyers to remind viewers of the similar coinage struck by Antiochos IV. This was done as a way of stressing Alexander’s claim to be Antiochos IV’s son: it did not do Balas much good in the end since soon after this coin was struck he was deposed by the forces of Demetrios II and, after his flight in 145 BC, murdered by his own officers.
