Some copper coins dating from the reign of Saltuk, who died in Rajab 563/M ay 1168, and his son Abu’l-Fath Mehmed are interesting like those of neighbouring principalities, not only because of their fidelity to Byzantine types in showing St George, but also because of the orthography, which is given in all the chronicles as Saltuk, but here as Salduk. They also bear the names of the Iranian sultans Mascud and Tughril, which signifies that the Saltukids of that period still considered themselves as being in some way in the Great Seljuk sphere of influence.
