A medieval ring that was discovered by a UK metal detectorist has sold at auction for £12,000 ($18,261).
The 24-carat gold ring was found by Peter Beasley while traversing a field near the village of Buriton in Hampshire.
The British Museum has confirmed that it belonged to William the Conqueror's eldest son, Robert Curthose, Duke of Normandy (c.1054-1134).
Remarkably, this is far from the first important find that Beasley has made. In 1996, he discovered 250 Roman coins, which he sold to the British Museum for £100,000 ($152,175), and a Roman gold pendant, which is inscribed with the letter "Ti Ceasar" and dates to the 1st century AD.
