EDXRF and XPS characterizations of a recently found Selinunte ancient coin are presented. Such a coin was found as essentially made up by a Sn-Pb alloy and its types have a very strong similarity with those shown by a silver set issued in the same historical period. It has been also studied by means of a SEMEDXRF coupled apparatus in order to have information about the compositional inhomogeneity of the alloy. XPS measurements have been used to provide a more surface sensitive analysis. The different probing depths of the adopted techniques have been found useful in evidencing volume inhomogeneities of the sample, at least in the first few microns above its surface. From an archaeological point of view, the coin may be ascribed to a coinage for funerary use or, more probably, to a coin production carried out during the difficult economic period of the history of Selinunte, immediately preceding the year 409 b.C., when the city was destroyed by Carthaginian armies.
