Tetradrachm In the name of Alexander III

Struck at Alexandria in the years immediately following the death of Antigonus's son Demetrius at Gaza in 312 BC, this issue belongs to the earliest phase of Ptolemy I's coinage — still produced in the name of Alexander III rather than the new satrap himself. Ptolemy would not formally claim the royal title until 305/304 BC, and the continued use of Alexander's name was a deliberate political calculation, lending legitimacy to a regime that needed it.

The Lorber 1.1 classification places this among the foundational types of Alexandrine-style coinage produced under Ptolemaic authority before the tradition diverged sharply from Macedonian norms.
