Identificazione di osservabili utili all’individuazione di falsi nell’ambito dei reperti metallici di interesse archeologico

Identification of parameters useful for the identification of fakes of metal artefacts of archaeological interest was studied. The trade of artifacts, in particular coins and jewels, involved a tremendous amount of money with a relatively high probability of buying a fake or a counterfeited object. The impedance spectra were recorded at the open circuit potential by applying a sinusoidal signal 10 mV in amplitude in the frequency range 100 kHz to 10 mHz.
