Antigonos I, one of Alexander’s principal successors, controlled much of Asia Minor and the Levant in the decade before Ipsos (301 BC). His administration continued the Alexander tetradrachm type at key mints such as Sidon to ensure a stable, widely accepted silver currency for military pay and regional commerce while maintaining political continuity with Alexander’s legacy.
