Abdagases I was an Indo-Parthian king, a nephew of Gondophares evident from some of his coins, who ruled during the first decades of the 1st century AD. Though he never assumed the title of Gondophares, he was the an important successor of his uncle, ruling his Indian conquests.
The bilingual coin illustrated here exhibits the kharoshti script where it can be read as "Gudaphara brathaputrasa maharajasa Abadagashasa." Brathaputra means nephew in Prakrit, the language in the coin. Zeus is also depicted in the same face.
