In 2014 local metal-detectorist Darrin Simpson found a coin minted during the reign of Æthelberht II of East Anglia (died 794), in a field near the town. It is believed that the minting of these coins may have led to Æthelberht's beheading by Offa of Mercia, as it had been struck as a sign of independence. Describing the coin, expert Christopher Webb, said, "This new discovery is an important and unexpected addition to the numismatic history of eighth century England."
