A new noninvasive method has revealed the origins of silver coins dating back to the early medieval period, shedding light on currency changes in Europe.
Human-made currency such as coins and paper bills have certainly evolved over time. Small pieces of precious metals or paper with no metal backing have changed into invisible cryptocurrencies stored on servers. For decades, numismatists–or currency experts–have puzzled over where the silver present inside some coins uncovered in England came from. The coins date back to between 660 and 750 CE, when the Anglo-Saxon world began to see a large revival of trade using silver coins .
No known source of European ore matches the elemental and isotopic characteristics of these early silver coins. According to the team, there is also no meaningful overlap with late Western Roman silver coins or other objects made from the metal, meaning that it was not simply recycled late Roman silver.
