Chemical and Discriminant Analyses of Augustan Asses

Sixty-nine Augustan asses from 16 BC to 12 AD were analysed by X-ray fluorescence for the elements, Fe, Co, Ni, Cu, Zn, As, Ag, Sn, Sb and Pb. The compositions varied significantly year by year. The earliest coins contained relatively high concentrations of Sb, Ag and Ni, whereas the last of these c...

Description
Summary:Sixty-nine Augustan asses from 16 BC to 12 AD were analysed by X-ray fluorescence for the elements, Fe, Co, Ni, Cu, Zn, As, Ag, Sn, Sb and Pb. The compositions varied significantly year by year. The earliest coins contained relatively high concentrations of Sb, Ag and Ni, whereas the last of these coins had very low antimony and silver contents. Discriminant analyses based on the chemical compositions enabled probable chronologies of most of the issues to be deduced. The chronology proposed in Roman Imperial Coinage was confirmed.
