ASIA MINOR. Uncertain. Tessera (Bronze, 21x24 mm, 6.10 g), Hellenistic or early imperial times, 3rd century BC-2nd century AD. Dolphin, viewed from above, swimming left. Rev. Blank. Struck in high relief and with an attractive turquoise patina. Very fine.
It is hard to assign a date to this tessera, but style and fabric are surprisingly artistic, and the turquoise patina adds additional charm to it.
