Between 638 and 641 A.H. (ca.1240-1243 AD.) a series of remarkable silver dirhams were struck in Kaykhusraw’s name at Sivas and Konya depicting a lion and sun. While coins with images are not unknown in Islamic lands, particularly in the centuries following the Crusades, Koranic strictures typically forbid representations of living things.
Several explanations of the lion and sun have been offered. One suggests that the images represent the constellation Leo, the astrological sign of Kaykhusraw's beloved Georgian wife Tamar. Another says that the lion represents Kaykhusraw and the sun Tamar.
