A rare golden fish believed by experts to be part of an ornate 7th century belt buckle, was discovered by Barry Shannon. A fisherman who has taken up a metal detecting hobby. Mr Shannon is a beginner. He said the discovery was one of his first since taking up metal detecting. He only started four days previously – and that was only his fourth time at it. But given his other pastime, Mr Shannon mistook the item for an everyday bit of fishing kit. It looked like a spinner you put on the end of a line to catch a fish to him.
