Question

What is the significance of the coins in knowing the history of India ?

Answer 1

Here is how a several centuries–old coin may rewrite a key chapter in the history of ancient India: In 1851, a hoard of gold coins issued by several kings from the Gupta dynasty was unearthed near the holy city of Varanasi, in northern India. The Guptas, who ruled from the 4th to 6th centuries AD, ushered in the Golden Age of ancient India, a blossoming of the arts and sciences that produced the concept of zero, a heliocentric astronomy, and the Kama Sutra.
