Abstract
The chemical composition of seven coins of Amir Wali of six dirhams par value (two types) minted in Astarabad in 769 and 75 Hijri (1368 and 1374 AD) was studied by x-ray fluorescent analysis using a portable TRACER 5i spectrometer. There were established the basic composition of the coin alloy and the quantitative content of the trace elements. The performed comparison with the coin alloys compositions of the preceding dynasties demonstrated continuity of minting technologies and similarity of ore sources used in the production of dirhams during the reign of Amir Wali in Astarabad. Based on the literary data of galenic ores composition mined in the Zenjan province, it is suggested that the raw material for coin mintage was extracted from a deposit located near the city of Damgan.
