BAILIWICK OF GUERNSEY, CHANNEL ISLANDS—A gold coin has been discovered at a Roman site on the island of Alderney, according to a BBC News report. The coin has been dated to the fourth century A.D., during the reign of the emperor Valens, who ruled from A.D. 364 to 378. Archaeologist Phil de Jersey said the coin will help researchers date the Roman occupation of the site. “It’s all adding to the picture of the intensive Roman settlement that was here,” he said.
