Sadly, Andragoras is one of the many rulers whose coinage was more widespread than his history. This particular coin was likely minted by him. Though it lacks the name “of Andragoras”, it contains the same mint mark as those coins that do.
Andragoras may have been the founder of Parthia, though certainly with an asterisk. Initially a satrap of the Seleukid Empire, he revolted in 245 BCE from Seleukos II Kallinikos. However, his independence didn’t last long. Soon afterwards, his new kingdom was invaded by Arsakes I, who conquered his territory bit by bit and eventually killed him.
