Kujula Kadphises
As they had done in Bactria with their copying of Greco-Bactrian coinage, the Yuezhi copied the coinage of Hermeaus on a vast scale, up to around 40 AD, when the design blends into the coinage of the Kushan king Kujula Kadphises. Such coins may provide the earliest known names of Yuezhi "yabgu" (a minor royal title, similar to prince), namely Sapadbizes and/or Agesiles, who both lived in or about 20 BC.
