A farmer in the Swiss town of Ueken saw something glinting out of a molehill on his cherry orchard and wound up unearthing “more than 4,000 bronze and silver coins dating back to ancient Rome,” the Guardian reports. The coins, which were minted between the reigns of Roman Emperors Aurelian and Maximian, were buried around the year 294 and never exhumed until the farmer stumbled across them in 2015. “The orchard where the coins were found was never built on. It is land that has always been farmed,” archaeologist Georg Matter said.
