A British man has made one of the largest ever finds of Roman coins by using a metal detector. The hoard of more than 52,000 coins dating from the 3rd Century AD was found buried in a field near Frome in Somerset. <br/><br/>The coins were found in a huge jar just over a foot below the surface by Dave Crisp, from Devizes in Wiltshire. Mr Crisp said after his metal detector gave a funny signal, he dug down 14 inch before he found what had caused it. <br/><br/>He said he put his hand in, pulled out a bit of clay and there was a little Radial, a little bronze Roman coin, very small, about the size of his fingernail. He said the coins were all contained in a single clay pot and it only measured 18 inch across, the coins were packed inside and would have weighed an estimated 160kg. <br/><br/>Mr. Crisp reported the find to the authorities, allowing archaeologists to excavate the site.
