TYPE Ancient Greece, Pergamene Kingdom, reign of Eumenes II (197-160 BC), silver tetradrachm, 16.37g DESCRIPTION . Obv: Laureate head of dynasty founder Philetairos to right Rev: Athena crowning Greek legend: FILETAIROU, trident in left field, "sigma-omega" to the right of it, bow in right field REFERENCE: cf. SG 7225-6 GRADING: EF, broken and repaired (crack affects no obv. and little rev. design), toned ORDER INFO: G1114, $375 At some point during Eumenes' reign - ca. 180-160 BC, and possibly even earlier - Pergamum ceased to issue royal tetradrachms of the Attic standard, and moved to the well-known cistophoric tetradrachms tied to the Roman monetary system. Styllistically, the present piece appears to belong to the final phase of the old issues, with a remarkable Hellenistic style on both sides. Characteristically, the portait of the dynasty founder departs here from the customary heavy, bull-necked earlier renditions, and the delicate style even subtly suggests features of the reigning ruler, by the same hand as in his famous unique portrait tetradrachnm (SG 7224; for discussion, see ANS Museum notes 27 - R. Bauslaugh: "The unique portrait tetradrachm of Eumenes II").
