LONDON A treasure hunter has found about 52,500 Roman coins, one of the largest such discoveries ever in Britain, officials said Thursday.
The hoard, which was valued at 3.3 million pounds ($5 million), includes hundreds of coins bearing the image of Marcus Aurelius Carausius, who seized power in Britain and northern France in the late third century and proclaimed himself emperor.
Dave Crisp, a treasure hunter using a metal detector, located the coins in April in a field in southwestern England, according to the Somerset County Council and the Portable Antiquities Scheme.
The coins were buried in a large jar about a foot (30 centimeters) deep and weighed about 160 kilograms (350 pounds) in all.
Crisp said a "funny signal" from his metal detector prompted him to start digging.
