Penny - William I Bonnet type

The Bonnet type is one of the more puzzling issues of William's English coinage — named for the distinctive headgear on the obverse, it was struck at a relatively small number of mints for a short window roughly coinciding with the suppression of northern rebellions and the Harrying of the North in 1069–70. Whether mint output contracted due to the upheaval or simply because the type was always intended as a transitional issue is unresolved. Spink 1251 places it firmly within the sequence between the Profile Left and Canopy types.
