Precious metals were scarce during the decline of the Roman Empire in Germanic Europe, which would explain the recent discovery of a hoard of "gold coins and pieces of silver tableware which had been deliberately cut up (hacksilver)" in a field near Limburg in the Netherlands. (photos)
The coins found in the Echt Hoard show images of Emperor Constantine III, dating the artifacts to the 5th century.
From the Past Horizons archaeology blog:
The Echt hoard is a find with a special story and it represents a unique document for the final period of Roman rule in the Netherlands. The fact that the complete hoard could be salvaged through a full excavation means that the context was not lost. The concentration of gold hoards from this period seems especially connected to the frantic attempts of Emperor Constantine III to maintain a grip on the border defence in the lower Rhine region. However, in hindsight, the end of the Roman Empire was, by this time, a forgone conclusion.
