N2 - A combination of laser ablation ICP-MS and laser ablation ICP-AES has been utilised for the multielement analysis of coins. The approach involves the use of diamond lapping film for in situ sampling of metallurgical CRMs (for quality control) and coins. Rapid multielement analysis (B, Al, V, Cr, Mn, Ni, Co, Cu, Zr, Nb, Mo, Pb) of transferred steel standards resulted in precision of the order of 10% and detection limits in the range of 0.004-1.23μg/g. The Roman coins (317-378AD) were found to contain a greater range of trace elements at higher concentrations than the modern coins (1984-2000). Relatively high concentrations of As (598-2161μg/g), Ag (201-2215μg/g) and Sb (344-1425μg/g) were detected within the Roman coins. Furthermore, lead isotope ratio (207/206Pb, 208/206Pb) measurements for the ancient coins were performed with precisions between 2-5%.
