The Alchon were noted for their distinctive coins, minted in Bactria in the 5th and 6th centuries. The name "Khigi", inscribed in Bactrian script on one of the coins, and "Narendra" on another, have led some scholars to believe that the Hephthalite kings Khingila and Narana were of the AlChoNo tribe. They imitated the earlier style of their Hephthalite predecessors, the Kidarite Hun successors to the Kushans. In particular the Alchon style imitates the coins of Kidarite Varhran I (syn. Kushan Varhran IV).
