X-ray fluorescence analysis on a group of coins from the ancient roman city of Tridentum (Trento, Italy)

A group of 83 coins, found in the archeological excavations of the ancient Roman city of Tridentum (Trento, Italy), was studied for the determination of their composition, finalized to their classification and cataloging. The coins,mainlymade of copper-based alloys, were minted between the republican period (II century BC) and the last decades of the western empire (V century AD). The X-Ray Fluorescence archaeometric analysis has allowed a revision of the typological classification of the coins through the identification of six broad groups, each one characterized by a peculiar composition of the coins in the group. A tentative assignation of all the unreadable coins to one of the groups identified was proposed, in a way that could suggest also a possible dating of these coins.
