"Antioch on the Persian Gulf" is the name given by Otto Mørkholm to an uncertain eastern mint. He identified this mint as
the Seleucid refoundation of Alexandria on the Erythrean Sea (the later Charax Spasinou), but it is unclear that this attribution
is correct. The attribution was retained in parentheses in Seleucid Coins, Part 2. The coins of this mint seem to have exclusively
Susian provenances.
