Tetradrachm - Lason In the name of Alexander III

Chios was one of several eastern Greek mints that continued striking Alexander-type tetradrachms well into the second century BC, long after the Macedonian kingdom itself had fractured. These posthumous issues were not nostalgic — they were commercial instruments, accepted across the eastern Mediterranean trade networks precisely because the Alexander type carried universal recognition. The Chian series is distinguished by its local magistrate names, of which Lason is one of the documented signing officials placing this issue within a tightly catalogued civic sequence.

Price 2435 situates this among the later Chian posthumous issues, consistent with the period when Rome's victory at Magnesia in 190 BC had fundamentally restructured power in Ionia.
