Andy Falconer made the “once in a life time discovery” when out searching with fellow treasure hunter Rob Farrer.
The 47-year-old said: “I had no idea what it was at first but when I showed Rob his eyes lit-up.”
Mr Farrer, 59, a metal detectorist for 30 years, said: “I couldn’t believe it. I honestly think it is the most important object to be found in the Isle of Man this century and certainly the only one of its kind.”
