Parthian coinage
Parthian coinage was produced within the domains of the Parthian Empire. The coins struck by the Parthians were mainly made of silver, with the main currencies being the drachm and tetradrachm. The tetradrachm, which generally weighed around 16 g, was only minted in Seleucia, first conquered by the Parthians in 141 BC. Design-wise, Parthian coinage was based on Seleucid and Achaemenid satrapal coinage.
