Argolis. Argos in the Achaean League (?). Diobol. Circa 2nd century BC (Silver, 10.6 mm, 1.17 g). Helmeted head of Athena right, bowl decorated with coiled serpent. Rev. Large A within laurel wreath. BCD Peloponnesos -. BMC -. HGC 5, -. Lightly toned, slightly clipped. Very Fine. Unpublished and seemingly Unique. This attribution is tentatively based on the reverse type large A, which strongly point to the mint of Argos in the Peloponnesos. However, the late style of Athena's head, combined with the laurel wreath on the reverse, suggests an issue struck for the Achaean League: a federation of city-states in the northern Peloponnese, formed to promote mutual defense and economic cooperation, particularly active during the Hellenistic period.
