Saurashtra was a one of the original Janapadas located in Gujarat. It was one of the last Janapadas to fall - it was annexed to the Mauryan Empire only during the reign of Chandragupta Maurya (ca.300 BC). The scarce coins of Saurashtra were quite different from most other Indian coins of those times - there were struck using a single die, and were usually restruck with a new design on one or more occasions, resulting in quite a mess, like the one seen on this coin.
