Orio Malipiero’s and Enrico Dandolo’s denarii: surface and bulk characterization

Average and core silver content of ancient-debased coins via neutron diffraction and specific gravity

“…Among the latest non-destructive techniques developed as archaeometrical tools one can mention mass spectrometry coupled with laser ablation (LA-ICP-MS: Sarah et al 2007;Sarah 2008;Blet-Lemarquand et al 2009), X-ray fluorescence (XRF: Walker 1980;Kasztovszky et al 2005), and particle induced X-ray emission (PIXE: Bugoi et al 1999;Ager et al 2013) as techniques for testing the surface composition of ancient coins. In contrast, prompt gamma activation analysis (PGAA: Kasztovszky et al 2005;Corsi et al 2015;Corsi 2015), Fast Neutron Activation Analysis (FNAA: Guerra and Barrandon 1998) and all the various neutron analyses (Calliari et al 2013;Canovaro et al 2013;Kirfel et al 2011;Xie et al 2004;Kockelman et al 2003) provide results on the overall coin volume. Remarkable, even if not fully non-destructive, is the latest work of Butcher and Ponting (2015).…”

A Review of Energy Dispersive X-Ray Fluorescence (EDXRF) as an Analytical Tool in Numismatic Studies

“…Finally, Venetian coins (denarii) issued by the Doge Orio Malipiero and by the Doge Enrico Dandolo were examined by Calliari et al 35 The coins were analyzed without any preparation by using an EDXRF spectrometer, equipped with a Rh anode and a secondary target of Gd operating at 55 kV and 2 mA. The standardless Fundamental Parameter method was used to determine the compositions on both obverse and reverse.…”
