Stater - Andragoras

Andragoras was the Seleucid-appointed satrap of Parthia who, sometime around 245 BC, declared independence from the weakening Seleucid Empire during the turmoil following the death of Antiochus II. His autonomous coinage — this stater among it — had an extraordinarily short window of issue. By around 238 BC, the Parni tribe under Arsaces I invaded and killed Andragoras, ending his rule entirely and founding the Arsacid dynasty that would become the Parthian Empire. Survivors of his coinage are rare precisely because that window collapsed violently.
