News broke in November that a team of archaeologists had uncovered a riverside trove of over 5,500 silver coins in Augsburg, Germany, which they believe were buried around 1,800 years ago. The Roman era coins are denarii, which was the standard silver currency during the 1st to early 3rd centuries. The youngest coin in the hoard was minted at the beginning of the third century.

The coins were discovered scattered in a recently dug pit, although this wasn't their original location. Their original burial place was most likely washed away by a flood of the Wetach River centuries ago, scattering the coins amid the river gravel. Archaeologists believe the trove was first buried outside of the Roman city of Augusta Vindelicum in the early third century, although why the cache was concealed in the first place will most likely forever remain a mystery.
