In November 2001, metal detectorist Cliff Bradshaw stumbled upon this crushed gold cup in a field near Sandwich, England, which turned out to be a Bronze Age chalice dating from 1700-1500 BC.
The following year, the chalice was snapped up by the British Museum for £270,000 ($391k), or approximately $631,000 (£507k) in today's money. The cash was split between Bradshaw and the landowner.
