More than 30,000 silver coins have been found by archaeologists working at the site of a new city-centre hotel. The hoard, believed to date from the third-century, was unearthed about 450 feet from the historic Roman Baths. Experts believe the “treasure trove” is the fifth largest hoard ever discovered in Britain and the largest from a Roman settlement. The coins, which have now been sent to the British Museum for further analysis, are fused together in a large block. This makes identification and counting difficult and conservators at central London Museum expect the task of analyzing the coins to take up to 12 months.
