摘要:Abstract(#br)Superstition has it that tossing coins into wells or fountains brings good luck, thereby causing a potential accumulation of microbially contaminated metal particles in the water. Here, we characterized the microbiota and the resistance profile in biofilm on such coins...

摘要:... We investigated the irradiation of yttrium sputtered niobium coins and compared the yields and separation efficiency to solid yttrium coins. The sputtered coins were irradiated with an incident beam energy of 17.5 MeV or 17.8 MeV providing a degraded transmitted energy throu...

摘要:Abstract(#br)Voltammetry of microparticles (VMP) and electrochemical impedance spectroscopy (EIS) techniques, complemented by SEM-EDX and Raman spectroscopy, were applied to a set of 15 Roman bronze coins and one Tessera from the temple of Magna Mater (Rome, Italy). The archaeolo...

摘要:Abstract(#br)X-ray fluorescence (XRF) spectrometry is known as excellent nondestructive technique for analysis of artifacts, in our case, medieval numismatic coins. Collections of 30 silver coins, owned by National Museum in Belgrade, were investigated during our research. Coins...

摘要:Abstract(#br)Objectives(#br)Coins are the commonest foreign body ingested in paediatric populations. Although most ingested coins are either spontaneously passed or retrieved with medical intervention without serious consequence, there is potential for serious morbidity and mort...

摘要:... This find was composed of 7327 silver-copper coins. They seem to have been struck over more than one century, between the end of the 15th and the beginning of the 17th century. This hoard is an exceptional find composed of a large quantity of coins from various periods, areas...

摘要:Abstract(#br)The study of chemical composition and microstructural features of ancient coins provide researchers with invaluable and priceless information which can contribute to forgery detection. This study was conducted on nine copper and bronze coins preserved in a private co...

摘要:Abstract(#br)Thirty-three Byzantine copper-based coins (so-called anonymous follis ) from 970 to 1085 CE were investigated in order to determine the elemental composition both of the bulk and of the surface. The ancient coins analysed - belonging to the Thomas Bertelè Collec...

摘要:Abstract(#br)Archaeological surveys and metal detector prospecting yield a great amount of coins from the medieval period. Naturally, some of these are counterfeit which an experienced numismatist can determine without using chemical methods. The production of counterfeit coins...

摘要:Abstract(#br)The material study of ancient coins is very often rendered particularly challenging by several factors: the presence of surface alteration products; the occasional or deliberate, e.g., forgery, changes in the composition of the base alloy; the misleading informatio...
