Tetradrachm - Diophanes In the name of Alexander III

Rhodes issued Alexander-type tetradrachms not from imperial obligation but from commercial necessity — the island's position as the dominant trading hub of the eastern Mediterranean required coinage that foreign merchants would accept without question, and the posthumous Alexander type remained the most trusted silver denomination in Aegean commerce well into the second century BC. The magistrate name Diophanes appears on a small cluster of issues within this sequence, placing production in the years immediately following the catastrophic earthquake of 227 BC's long economic recovery and the shifting political pressures of Rome's expanding presence after Magnesia in 190 BC.
