A shadowy historical figure, Skostokos I is known only via numismatic evidence. He is considered as a satrap of Lysimachus due to the fact that his silver coins mirror the King’s earlier tetradrachmai. These coins were most likely, according to Youroukova and Mørkholm, struck immediately after Lysimachus’s death. Skostokos is thought to have declared his independent rule over the area surrounding Kabyle, what is today eastern central Bulgaria. That being said, while a number of his bronze coins were found near Kabyle, silver coins of this type have reportedly been found as far south as Sestos. That coupled with the herm control mark under Athena’s throne led Youroukova to speculate as to the existence of a mint at Ainos. W. Fischer-Bossert disagrees however. He speculates that the mint was actually located in the upper Hebros Valley north of the Rhodope closer to Kabyle.
