most part, are very numerous. The devices are almost entirely Greek, and must have been engraved by Greeks, or Indians trained in the Greek traditions. The rare gold staters and the splendid tetradrachms of Bactria disappear. The silver coins of the Indo-Greeks, as these later princes may conveniently be called, are the didrachm and the hemidrachm. With the exception of certain square hemidrachms of Apollodotos and Philoxenos, they are all round, are struck to the Persian (or Indian) standard, and all have inscriptions in both Greek and Kharoshthi characters. Coinage of Indo-Greek Kingdom began to increasingly influence coins from other regions of India by the 1st century BCE. By this time a large number of tribes, dynasties and kingdoms began issuing their coins; Prākrit legends began to appear. The extensive coinage of the Kushan Empire (1st–3rd centuries CE) continued to influence the coinage of the Guptas (320 to 550 CE) and the later rulers of Kashmir. During the early rise of Roman trade with India, up to 120 ships were setting sail every year from Myos Hormos to India. Gold coins, used for this trade, was apparently being recycled by the Kushan empire for their own coinage. In the 1st century CE, the Roman writer Pliny the Elder complained about the vast sums of money leaving the Roman empire for India: The trade was particularly focused around the regions of Gujarat, ruled by the Western Satraps, and the tip of the Indian peninsular in Southern India. Large hoards of Roman coins have been found and especially in the busy maritime trading centers of South India. The South Indian kings reissued Roman-like coinage in their own name, either producing their own copies or defacing real ones in order to signify their sovereignty. The Sakas (200 BCE – 400 CE) During the Indo-Scythians period whose era begins from 200 BCE to 400 CE, a new kind of the coins of two dynasties were very popular in circulation in various parts of the then India and parts of central and northern South Asia (Sogdiana, Bactria, Arachosia, Gandhara, Sindh, Kashmir, Punjab, Haryana, Rajasthan, Uttar Pradesh and Bihar). These dynasties were Saka and The Pahlavas.After the conquest of Bactria by the Sakas in 135 BCE there must have been considerable intercourse sometimes of a friendly, sometimes of a hostile character, between them and the Parthians, who occupied the neighboring territory.
