A medieval coin from the reign of William the Conqueror is being hailed as unique by experts. Discovered in a field near Gloucester, the hammered silver coin was found by metal detectorist Maureen Jones in November. Experts from the Portable Antiquities Scheme said the coin “filled in the hole” in the dates the Gloucester mint was known to have been operating. Dating from 1077-1080, the coin features the name of the moneyer “Silacwine”. There were no known examples of William I coins minted in Gloucester between these dates. The fortunate finder of the coin, Ms Jones, is a member of Taynton Metal Detecting Club and her unique find is to be returned to her shortly.
