Amateur metal detector finds pounds 100k necklace.
Maurice Richardson, 55, from Newark, Notts, found the solid gold torc in a ploughed field on a farm near his home.
The self-employed tree surgeon thought he had found a piece of scrap metal when he came across the twisted necklace, weighing 1. 5lb.
He lay on his stomach to scrape away the soil and found the Iron Age artefact, in near pristine condition, buried 2ft below the surface.
The coroner, who is expected to open a treasure trove inquest into the find, has said it could be worth more than pounds 100, 000.
Mr Richardson, who has been metal detecting for more than 30 years, has never found anything worth more than pounds 100 before.
He bought his metal detector for pounds 75 in 1970 and found a modern gold ring worth pounds 80 the next day.
