The coins of Rudrasiṃha are of a beautiful type of good workmanship and with clear legends. The legend in old Nágarí character reads:
राज्ञो महाक्षत्रपस रुद्रदामपुत्रस राज्ञो महाक्षत्रपस रुद्रसिंहस
Rájño Mahákshatrapasa Rudradámaputrasa Rájño Mahákshatrapasa Rudrasiṃhasa.
Of the king the great Kshatrapa Rudrasiṃha son of the king the great Kshatrapa Rudradáma.
Rudrasiṃha had also a copper coinage of which specimens are recorded from Málwa but not from Káthiáváḍa. Pandit Bhagvánlál had one specimen from Ujjain which has a bull on the obverse with the Greek legend round it and the date 117. The reverse seems to have held the entire legend of which only five letters रुद्रसिंहस (Rudrasiṃhasa) remain. This coin has been spoilt in cleaning.
To Rudrasiṃha’s reign belongs the Gunda inscription carved on a stone found at the bottom of an unused well in the village of Gunda in Hálár in North Káthiáváḍa.[75] It is in six well preserved lines of old Nágarí letters of the Kshatrapa type. The writing records the digging and building of a well for public use on the borders of a village named Rasopadra by the commander-in-chief Rudrabhúti an Ábhíra son of Senápati Bápaka. The date is given both in words and in numerals as 103, ‘in the year’ of the king the Kshatrapa Svámi Rudrasiṃha, apparently meaning in the year 103 during the reign of Rudrasiṃha. The genealogy given in the inscription is: 1 Chashṭana; 2 Jayadáman; 3 Rudradáman; 4 Rudrasiṃha, the order of succession being clearly defined by the text, which says that the fourth was the great grandson of the first, the grandson of the second, and the son of the third. It will be noted that Dámájaḍaśrí and Jivadáman the fifth and sixth Kshatrapas have been passed over in this genealogy probably because the inscription did not intend to give a complete genealogy but only to show the descent of Rudrasiṃha in the direct line.
Kshatrapa VIII. Rudrasena, a.d. 203–220.The eighth Kshatrapa was Rudrasena, son of Rudrasiṃha, as is clearly mentioned in the legends on his coins. His coins like his father’s are found in large numbers. Of forty in Dr. Bhagvánlál’s collection twenty-seven bear the following eleven[76] dates, 125, 130, 131, 132, 133, 134, 135, 136, 138, 140, 142. The coins are of the usual Kshatrapa type closely like Rudrasiṃha’s coins. The Nágarí legend reads:
राज्ञो महाक्षत्त्रपस रुद्रसिंहस पुत्रस राज्ञो महाक्षत्रपस रुद्रसेनस
Rájño Mahákshatrapasa Rudrasiṃhasa putrasa Rájño Mahákshatrapasa Rudrasenasa.
Of the king the great Kshatrapa Rudrasena son of the king the great Kshatrapa Rudrasiṃha.
