Résumé

This paper proposes an application of the LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) method of analysis to the study of Roman silver coins. The first part presents the characteristics of the LA-ICP-MS method applied in Orléans for the analysis of Roman silver coins. The second part consists of case studies. The selected examples date from the second half of the first century BC (the Augustan Age). In this period, the workshops minting denarii and quinarii are numerous and sometimes very distant from each other, which allows interesting comparisons between coins from different places. The metallic composition of official Roman silver denarii whose places and dates of minting are known is also compared to similar denarii, but which present technical peculiarities from a numismatic point of view that suggest that they are unofficial coins, forgeries, or out-of-standard examples. The aim is to see whether the numismatic approach and the archaeometric approach agree or diverge. The results of the LA-ICP-MS method for Roman silver coins are thus tested experimentally. This paper also provides new information on the manufacturing conditions of atypical coins.
