Kharohostes' coinage bear a dynastic mark (a circle within three pellets), which is rather similar, although not identical, with the dynastic mark of the Kushan ruler Kujula Kadphises (three pellets joined together), which has led to suggestions that they may have been contemporary rulers.
Some coins used the portrait, name and title of the Indo-Greek king Hermaeus on the obverse, indicating Kujula's wish to relate himself to the Indo-Greek king.

This invasion of Kujula Kadphises is thought to have occurred during the reign of Abdagases and Sases, the successors of Gondophares, after 45 CE.
The name "Κοζουλο" was also used by the first Kushan ruler Kujula Kadphises (Greek: Κοζουλου Καδφιζου, Kozoulou Kadphizou or Κοζολα Καδαφες, Kozola Kadaphes), which may suggest some family connection.
The first Kushan emperor Kujula Kadphises ostensibly associated himself with Hermaeus on his coins, suggesting that he may have been one of his descendants by alliance, or at least wanted to claim his legacy.
