“…High silver content of these coins is evident that finds check in the other analyses of silver coins recovered in the other regions [35,37]. These surface features confirm the chemical composition: it is well known that in one silvercopper alloy, as the silver content comes down under 90%, the alloy will separate into two distinct phases; one is copper-rich and the other is silver-rich, the proportion of these phases being determined by the alloy composition [35,38].…”

This work enters in an interdisciplinary research project involving the archaeometrical analysis of ancient silver coins minted in the Greek colony of Taras (the modern south Italian town of Taranto) between the V century BC and the III century BC. In this work, by comparing the results obtained from X-ray microanalysis data acquired from the least corroded surface areas and the cross-section of coins from SEM-EDX and from XRF analysis, we have demonstrated that analysed coins exhibited a corrosion layer no more than 25 μm and that surface silver enrichment was less than 1 wt%. Thus, the data obtained by using X-ray microanalysis from surface may not significantly differ from the original bulk composition. Our results demonstrate that the silver content in the coins decreases considerably ranging from about 97% for the older down to 80% for the ones of 3rd Evans period (300–270 BC), corresponding to the significant social change in the period.

“…Furthermore, silver coins dating back to the 3rd century B.C. from the Illyrian King Monounios were studied by Pistofidis et al, 39 who observed that these coins have different chemical compositions and different microstructures. The experimental EDXRF system consisted of a high voltage generator and a tungsten anode X-ray tube operated at 30 kV and 40 mA, and a Si(Li) detector, with resolution of 180 eV at Mn Ka.…”

“…9 (2023) millennium BC [6]. The Binary Alloy, which is composed of an alloy of silver and copper and named Bullion alloy [7] is one of the most popular silver alloys [8,9] and there is a percentage of impurities from tin, arsenic, lead, and antimony [10]. The corrosion process, which results in a brownishblack tarnish, is responsible for the deterioration of silver-copper alloys.…”

In this research, a set of four coin silver spoons that belong to prince Mohamed Ali and were struck in Egypt in the name of Sultan Abdul Hamid II (1293-1327 AH / 1876-1909 AD) is investigated. The set was exhibited at Prince Mohamed Ali Museum, in Cairo, Egypt. As it has never been studied before, the study aims to identify the manufacturing technique and the deterioration aspects. Visible imaging and geometrical documentation were undertaken to reveal the preservation condition of the objects. A USB Digital microscope was used to examine the coin spoons. Portable x-ray fluorescence (XRF) was used for the elemental analysis of the alloy, while Scanning Electron Microscopy coupled with energy dispersive X-ray (SEM-EDX) was used in order to identify the corrosion products. Metallographic Microscope was used to identify the alloy microstructure to explore the manufacturing technology. Portable x-ray fluorescence (XRF) showed that the coin spoons are made of coin silver, which is an alloy of silver and copper. While the results of scanning electron microscopy coupled with energy dispersive X-ray (SEM-EDX) confirmed the portable x-ray fluorescence analysis that the coin spoons were made of a silver-copper alloy, SEM-EDX analysis also showed the presence of elemental corrosion layers like C, S, and Cl. An investigation with metallography of the crescent-like shape at the end of the hand part of the coin spoon found that the hand area was cast then twisted, It was also revealed that the coin part had been cast first, and then struck afterwards, as seen by the cold-worked dendrites that were deformed.
