The Long Cross penny was introduced in 1247 under Henry III specifically to combat widespread clipping — by extending the cross to the coin's edge, any removal of silver became immediately visible. Class 5c falls within the mid-1250s recoinage period, when provincial mints at Canterbury, Durham, and Bury St Edmunds operated alongside London to meet demand. North 993 distinguishes this class by subtle lettering differences in the moneyer and mint inscriptions, the primary tool for attributing these otherwise visually similar issues.
