This counter mark was applied to a tetradrachm of Soter Megas by the Indo Sakas, reattributing the coin to Damazada (died SE 99/100, AD 177/178). The identification of this counter mark lead to serious difficulties understanding the chronology of the Ksatrapas.The C/M is: six arched hill on bust of king.
