In 2017, two Dutch discovered numerous Roman coins by the Aa River in Berlicum, in the south of the Netherlands. The latest research by scientists suggests that they could have served as payment for crossing the river.
A total of 109 coins were discovered that were minted between 27 BCE and 180 CE. Coins were found in a larger area along the river, and what’s more, they were of little value in ancient times (no gold coin was discovered). Hence the hypothesis that for years people have been crossing the ford in this place, and coins were lost during the crossings.
