Gupta

The Gupta script, which is also known as the Gupta Brahmi Script
or the Late Brahmi Script, was used for writing Sanskrit in the Gupta
Empire, which existed from about 320 to 550 AD. It developed from the
Ashokan Brahmi script, and developed into the Devanagari, Sharada and
Siddham scripts

Gupta inscriptions have been found mainly on iron or stone pillars,
and on numerous gold coins from the Gupta Dynasty.
