Brodie was out with Gloucestershire Metal Detecting Club when he found a rare 14th Century seal just metres from the family car and an inch underground. Brodie said in the future he hoped to find something “really big”, like a Roman sword.

Gloucestershire and Avon Finds Liaison Officer Kurt Adams said it was probably an ecclesiastical seal, with the lamb of God pictured on the front and a banner behind that read: “Roger of Tetbury”. “It’s a lovely find, and a really good quality one as well,” he added.

Because the seal was not classed as treasure, Brodie is able to keep it and has already set his sights on something bigger.

“I always dream of finding something really big, like a horse and carriage or something, like gold jewellery or Roman swords and hats”, Brodie said.
