The study of the elemental composition of silver coins of the Ilkhanid period can help explain the locations and identification of coin mines. It also provides information regarding the economic and political conditions of the time period under study. The aim of this work is to study the chemical composition of certain Ilkhanid coins in order to determine any connection between the mines used for extraction of the silver and the actual silver coins minted at that time. Using the PIXE technique, the metallic elements Fe, Cu, Zn, As, Ag, Au, and Pb were analysed.
