Indian rupee

 The history of the Indian rupee traces back to ancient India in the 6th century BCE; ancient India was one of the world's earliest issuers of coins, along with the Chinese wen and Lydian stades. Arthashastra, written by Chanakya, prime minister to the first Maurya emperor Chandragupta Maurya, mentions silver coins as rpyarpa; other types, including gold coins (suvararpa), copper coins (tamrarpa), and lead coins (ssarpa), are also mentioned. Rpa means 'form' or 'shape'; for example, in the word "rpyarpa," rpya means "wrought silver," and rpa means "form."
