It will be noted that in this coin both Rudrasimha and Dámasiri are called great Kshatrapas, while in his own coin and in the coins of his son Yasadáman, Rudrasimha is simply styled Kshatrapa. It is possible that Dámasiri may have been more powerful than Yasadáman and consequently taken to himself the title of Mahákshatrapa. The application of the more important title to a father who in life had not enjoyed the title is not an uncommon practice among the later Kshatrapas. The rarity of Dámasiri's coins shows that his reign was short. After Dámasiri comes a blank of about thirty years. The next coin is dated 270. The fact that, contrary to what might have been expected, the coins of the later Kshatrapas are less common than those of the earlier Kshatrapas, seems to point to some great political change during the twenty-seven years ending 270 (A.D. 321-348). [Kshatrapa XXIV. Rudrasena, A.D. 348-376.] The coin dated 270 belongs to Svámi Rudrasena son of Svámi Rudradáman both of whom the legend styles Mahákshatrapas. The type of the coin dated 270 is clearly adapted from the type of the coins of Yasadáman. Only two of Rudrasena's coins dated 270 are recorded. But later coins of the same Kshatrapa of a different style are found in large numbers. Of fifty-four in the Pandit's collection, twelve have the following dates 288, 290, 292, 293, 294, 296, and 298. The difference in the style of the two sets of coins and the blank between 270 and 288 leave no doubt that during those years some political change took place. Probably Rudrasena was for a time overthrown but again came to power in 288 and maintained his position till 298. Besides calling both himself and his father Mahákshatrapas Rudrasena adds to both the attribute Svámi. As no coin of Rudrasena's father is recorded it seems probable the father was not an independent ruler and that the legend on Rudrasena's coins is a further instance of a son ennobling his father. The legend is the same both in the earlier coins of 270 and in the later coins ranging from 288 to 298. It reads: Rájño Mahákshatrapasa Svámi Rudradámaputrasa Rájño Mahákshatrapasa Svámi Rudrasenasa. Of the king the great Kshatrapa Svámi Rudrasena son of the king the great Kshatrapa Svámi Rudradáman. [Kshatrapa XXV. Rudrasena, A.D. 378-388.] After Rudrasena come coins of Kshatrapa Rudrasena son of Satyasena. These coins are fairly common. Of five in the Pandit's collection through faulty minting none are dated. General Cunningham mentions coins of Kshatrapa Rudrasena dated 300, 304, and 310. [145] This would seem to show that he was the successor of Rudrasena son of Rudradáman and that his reign extended to over 310. The legend on these coins runs: Rájño Mahákshatrapasa Svámi Satyasenaputrasa Rájño Mahákshatrapasa Svámi Rudrasenasa.
