On 9 April 2010, Dave Crisp found 21 coins while metal detecting on farmland near Frome. Two days later, he returned to the site and discovered a huge pot filled with more coins. Archaeologists believe the hoard will rewrite the history books. One of the most important aspects of the hoard is that it contains a large group of coins of Carausius, who ruled Britain independently from AD 286 to AD 293 and who was the first Roman emperor ever to strike coins in Britain. The hoard contains more than 760 of his coins, making it the largest group ever found. Among these coins are five rare examples of his silver denarii, the only coins of their type being struck anywhere in the Roman Empire at the time. This accessible book is written by experts from the British Museum and the Portable Antiquities Scheme. Packed with photography of the coins as well as images of the hoard in situ, this book will shed new light on 3rd-century Roman Britain. ”This find presents us with an opportunity to put Carausius on the map. School children across the country have been studying Roman Britain for decades, but are never taught about Carausius - our lost British emperor.” (Roger Bland).
