Ancient copper coins from Creek cities and confederacies such as Amphi
polis, Veroia, Dion, Edessa, Magnetes, Stobi, Apollonia, Kerkyra, Pell
a, Philippoi, Phoenike, and the Macedonian and Thessalian Koina, were
analyzed non-destructively by proton induced X-ray emission (PIXE) aft
er removal of the patina. The copper coins were minted during Roman Im
perial times (31 B.C.-268 A.D). Eleven elements were determined quanti
tatively. The correlation between the composition and the minting time
is examined. The results are compared with those of a previous study
for coins from the cities of Nikopolis in Epirus and Thessaloniki in M
acedonia, in the same period.
