Rudrasimha I was a Western Kshatrapa ruler, who reigned from 178 to 197 CE.
From the reigns of Jivadaman and Rudrasimha I, the date of minting of each coin, reckoned in the Saka era, is usually written on the obverse behind the king's head in Brahmi numerals, allowing for a quite precise datation of the rule of each king. This is a rather uncommon case in Indian numismatics. Some, such as the numismat R.C Senior considered that these dates might correspond to the much earlier Azes era instead.
