Investigation of Chemical Composition of the Alloy of 3rd Century Bosporan Billon Staters by XRF Analysis, Neutron Tomography and Diffraction
The results of combined investigation of the chemical composition of the Bosporan King Rhescuporis V's billon staters from the 2011 Phanagorian hoard by XRF spectroscopy, neutron tomography and diffraction, and metallographic analysis are presented. The study of the crystal structure of the coin alloy indicates there is no silver coating of staters minted from low-grade silver.
