One Sunday, over drinks, Reg Mead was told a story: that back in the fifties a farmer had unearthed a pot full of old coins. He’d scooped up what he could and then ploughed the rest back in to the field. Reg is a keen metal detectorist so his interest was piqued. He got permission from the landowner and set off with some friends from his metal-detecting club. But there was a catch, the land was very much in use so he could only search for four to five hours a year. After a while most club members gave up and moved on but Reg and his friend Richard Miles persisted, for thirty years.
