After conquering the Ksatrapa kingdoms in western India, Chandragupta started issuing silver coins which were very similar to the local currency in the region - the silver Ksatrapa coinage. The style and design was maintained with the Obverse showing the bust of the King, with the year and Greek letters. Reverse was changed to show a Gaurda bird which was the royal symbol of the Guptas.

This coin is the first of it's type of be discovered that was struck from a die used for striking full size gold dinars, but STRUCK IN SILVER metal. This specimen is in pure silver and shows signs of being struck from a die (vs. being a cast coin).
