This is a very worn coin : Pisidia, Isinda (probably the modern village of Kişla, west of Antalya in Turkey), time of king Amyntas (36-25 BC). AE 17.5-19 mm, 3.97 g. Obv.: Laureate head of Zeus, r. Rev.: ΙΣΙΝ, rider with spear galloping, r.; beneath, serpent; in l. field, Z RPC I, 3512g It is a series of bronze coins registered in the RPC database under nrs. 3512a to 3512t. All have the legend ΙΣΙΝ on exergue, and the numerals A (3512a) to KA (3512t). K seems to be missing. RPC knows two specimens of this coin, one from a public auction, another one from the British Museum collection. They have very different styles: The British Museum specimen seems to be double die-linked with my specimen. So is another specimen found on Vcoins : 3.68 g. This is a curious pair of dies... On the reverse the Σ and the N are retrograde, and on the obverse Zeus laureate has a bizarre hairstyle. Could it be seen as an imitation of the Roman denarii minted by the Calpurnii in 90 and 67 BC?
