Sometime around 660 CE, silver coinage replaced gold as the dominant form of currency in northwest Europe. But what was the source of all that silver? According to a recent paper published in the journal Antiquity, silver for the earlier post-Roman coins during this period came from Byzantine silver plate, while silver for the later coins most likely came from mines located in Melle, Aquitaine.
