British hammered, Normandy, Richard I, great-grandfather of William the Conqueror, denier 943-996

The monogram of this issue has been identified with that of Hughes de Calvacamp (c. 890-980) who was Archbishop of Rouen at the time of the issue. It therefore may be the product of an ecclesiastical mint. 

EF, good strike for this notoriously crude issue.
