Abstract  

Energy-dispersive X-ray fluorescence spectrometry was applied for the analysis of historical silver coins to determine the elemental composition in a fast and non-destructive way. Ag, Cu and trace elements (V, Cr, Mn, Fe, Co, Ni, Hg, Pd, Zr, Mo, Rh, Ru) were determined in coins of King Mathias (Hungary, 1458–1490). A new data evaluation technique was used to avoid the problems arising from the different sizes, surfaces and geometries. The appropriateness of this method was confirmed by analysing certified silver/copper standard alloys.
