Separating silver sources of Archaic Athenian coinage by comprehensive compositional analyses

This article demonstrates that distinct and coherent silver sources can be discriminated from surface compositional analyses. In the first large-scale study of Archaic (pre-479 BC) Athenian silver coins in museum collections around the world, we analysed 788 coins by Energy Dispersive X-ray Fluorescence (XRF) spectrometry with a mathematical correction to provide a reliable composition for key diagnostic elements. Principal Component Analysis...
