 Later issues of the Peroz design abandon the degraded Palhavi legend altogether as well as the "Sri" mark, and instead used a Brahmi legend "Rana Datasatya".Some later imitations of these coins after 480 CE may have been made by the Hephthalites, who added a Hunnic tamgha to the design, after they took over the northwestern Indian provinces.The quality of the coins also becomes very much degraded by that time, and the actual gold content becomes quite low.
