The correct answer is option 1 - Lead. The Satvahanas, an ancient Indian dynasty that ruled from the 2nd century BCE to the 3rd century CE, predominantly minted their coins in lead. Lead was a commonly used metal for coin minting during this period due to its abundant availability and ease of processing. However, it is important to note that the Satvahanas also minted coins in other metals like copper and silver. Lead coins of the Satvahana dynasty typically featured various symbols, including depictions of rulers, gods, and animals, along with inscriptions in Brahmi script. These coins played a significant role in trade and commerce during the Satvahana period and provide valuable insights into the economic and cultural history of ancient India.
