W Conte collection
North notes round Halfpennies, all of this type, from six mints, Hereford, No (Norwich ?), Oxford, Wallingford, Winchester and York (North 872). This coin adds Sandwich to the list.
One other round Halfpenny is known, a curious mule, also by Adalbot at Sandwich, using this obverse die and a type IX, cross in quatrefoil, Penny reverse die (North 872/1).
'The knowledge of only a single obverse and reverse design type for the Henry I halfpence, their stylistic uniformity, and their extreme rarity, all point to an issue of limited duration.' Conte and Archibald, 'Five Round Halfpennies of Henry I' in SNC September 1990, pp. 232-236
Estimate: £3,000 - £4,000
