“…Much of this iron can be removed during a secondary melting operation (refining), although some iron invariably remains in the metal. However, when performing surface analysis, most of the iron usually is related to incomplete removal of soil residues (Hajivaliei and Khademi Nadooshan 2012;Notis et al 2007) and iron content is therefore not discussed in this work.…”

This paper presents the micro-XRF analysis of over 100 Sasanian billon and copper coins from the collections of the Royal Museums of Art and History in Brussels, Belgium. This study discovered that some coins, thought to be copper, were actually billon coins. Furthermore, it illustrated the continuity in use and recipe of small copper coins from the Parthian into the Sasanian period. Previous research into the elemental composition of copper coins from the Sasanian period only spanned the period 224-309 CE, while this paper encompasses the whole period until the fall of the empire in 651 CE. The link with lead coins is also discussed.

“…Different analytical techniques like inductively coupled plasma-atomic emission spectrometry (ICP-AES), x-ray fluorescence spectroscopy (XRF), inductively coupled plasma-mass spectrometry (ICP-MS), and Energy Dispersive x-ray Analysis (EDX) are used for the elemental analysis of metallic objects. These techniques are more promising and give precise discernment of different elements/alloys used to prepare the coins [11][12][13][14][15][16][17][18][19]. However, these techniques need sample preparation or involve solvent/dissolution.…”

The present work aims to demonstrate the capabilities of Laser-induced Breakdown Spectroscopy (LIBS) coupled with a multivariate technique for rapid quantification and classification of old Indian coins made of various alloys. Thirteen old Indian coins in different years of circulation, (1922–1986) were selected for the study. The concentrations were determined by Calibration free LIBS (CF-LIBS) method. The concentration of cuprum (Cu) is negligible, and aluminum (Al) is maximum in the first five coins, and vice-versa in the remaining eight coins. Two different multivariate methods, Principal Component Analysis (PCA) and Soft Independent Modelling of Class Analogy (SIMCA) have been used to classify and identify the coins. PCA classified all thirteen samples into four main alloy categories. The discernment of unknown samples to their probable class membership of alloy was performed using SIMCA. The surface hardness (Brinell hardness number) is linearly correlated with the plasma temperature and LIBS intensity ratios. The sample surface of the first and fifth coin belongs to Al-alloy, having the least surface hardness, and it became harder for Cu-Ni alloy, Ni-brass alloy, and bronze alloy. The hardness of the surface is more for bronze sample twelve. It is also observed that the plasma temperature increases monotonically with the Brinell hardness number. This analysis provides valuable information on fabrication methodology and explains large diversification in the elementary composition of old coins.
