David Crisp, an amateur treasure hunter, found about 52,500 ancient Roman coins in a field in southwestern R England. Mr. Crisp used a metal detector to find the treasure. The coins were buried in a large clay pot that was about 30 centimeters deep and that weighed about 160 kilograms. Mr. Crisp first found several loose coins, but he resisted the temptation to dig up the whole pot. He contacted archaeologists, who excavated the contents. The coins were from the late third century A.D., and they are worth around S500,000. Crisp cannot keep the coins by law, but he gets some of the money from the sale of the coins to a museum.
