Coinage
Greco-Bactrian coins also depict the kings wearing distinct headgear, such as helmets modelled on the Boeotian cavalry helmet of Alexander the Great, or the Macedonian kausia. This is unique to the Greco-Bactrian kings, who first featured such designs on their coins as other Hellenistic rulers are shown to only wear the diadem. As such the Greco-Bactrians are especially known for their innovative coinage designs. Further examples include the use of different metal alloys for their coins and the issue of bilingual coinage, using Greek on the obverse and an Indian language (such as Pali) in the Kharoshti or Brahmi scripts on the reverse. Local Indian symbols and deities are also depicted, i.e. Buddhist symbols and some Hindu deities (see Influence on Indian art subsection below). This syncretic design was first introduced after king Demetrius I of Bactria conquered areas of the Indian subcontinent between 190 and 180 BC, with king Pantaleon being the first to issue coins of the Indian standard, when the Greeks truly started ruling over Indian populations.
