N. Kallithrakaskontos et al., STUDY OF ANCIENT-GREEK COPPER COINS FROM NIKOPOLIS (EPIRUS) AND THESSALONIKI (MACEDONIA), Archaeometry, 35, 1993, pp. 265-278
Ancient copper coins from the Greek cities Nikopolis in Epirus and The
ssaloniki in Macedonia, minted during Roman imperial limes (31 BC to A
D 268), were analysed non-destructively by proton induced X-ray emissi
on, after removal of the patina. An intercomparison study using differ
ent analytical methods was also performed on five coins. Eleven elemen
ts were analysed quantitatively on all coins. Statistical analysis of
the results was performed for their presentation in the form of dendro
grams. Finally, the variations in the concentrations of some individua
l elements from emperor to emperor were examined.
