Di-Chalkon - Kujula Kadphises

Kujula Kadphises was the founder of the Kushan Empire proper, unifying the five Yabghus of the Yuezhi sometime in the early first century AD after centuries of fragmented nomadic confederation. His copper issues — among the earliest distinctly Kushan coinage — drew heavily from the coin vocabulary of the Indo-Greek and Indo-Scythian kingdoms he displaced, a deliberate act of monetary absorption rather than invention. The di-chalkon denomination itself is a Greek-derived unit, a surviving linguistic ghost of Bactrian Greek influence long after Greek political power had evaporated from the region.
