Writing from the numismatist point of view, the authors open this paper by reviewing critically the use of scientific methods for the studies of ancient coins. They also report about an application of the PIXE method at low incident proton energy to one of the most celebrated and known coinage in the ancient history: the Athenian silver coins of the fifth century BC. The results of those analyses indicate that the metallic composition of several coins usually taken as ancient imitations of Athenian coins does not differ from that of the genuine ones. Those analyses confirm what the authors have inferred from numismatic sources: These coins are probably genuinely Athenian. (C) 2004 Elsevier B.V. All rights reserved.
