They issued tetradrachms, which were silver coins, as a part of their currency system. These tetradrachms were typically of high silver content and were used widely in trade throughout the Mediterranean and Near East during the Hellenistic period.

The design of tetradrachms of the Seleucid Empire varied over time and depending on the ruling dynasty. They often featured the portrait of the ruling monarch on the obverse (front) side and a variety of symbols, gods, or scenes on the reverse (back) side.
