Struck at the great mint of Babylon in the years immediately following Alexander's death, this tetradrachm belongs to the vast posthumous coinage issued in his name under the successive authority of Archon, Dokimos, or Seleukos I as they jockeyed for control of the city and its satrapy in the chaotic years of the Diadochi. The obverse presents the youthful head of Herakles, the hero from whom the Argead kings claimed descent, shown in three-quarter profile to the right and crowned with the scalp and paws of the Nemean lion, its knotted forepaws tied beneath the hero's chin. The reverse carries the royal legend ΒΑΣΙΛΕΩΣ ΑΛΕΞΑΝΔΡΟΥ flanking an enthroned Zeus Aetophoros, seated left on a low-backed throne, a long scepter braced in his left hand while his right extends to support a perched eagle, the bird poised as though just alighted. The field bears the control marks M to the left of the throne and ΛY below, the bureaucratic fingerprints of the magistrates who oversaw production at this immensely prolific mint, which continued to strike in Alexander's name for years after his death precisely because his coinage had become the accepted international currency of the Hellenistic world, trusted by mercenaries, merchants, and treasuries alike regardless of who actually held the throne.
