Abstract
A combined PIXE and XPS analysis has been performed on a few Roman coins of the republican and imperial age. The purpose was to investigate via XPS th e nature and extent of patina in order to be capable of extracting PIXE dat a relative to the coins bulk. The inclusion of elements from the surface la yer, altered by oxidation and inclusion, is a known source of uncertainty i n PIXE analyses of coins, performed to assess the composition and the prove nance.
