NORMAN. Stephen. 1135-1154. AR Penny (19mm, 1.40 g, 8h). Voided Cross and Mullets type (BMC ii). Uncertain (Pevensey?) mint; [Al?]wine, moneyer. Struck circa 1145-1150. Crowned bust facing slightly left, holding scepter / [+ ...]PINE : O[N : ...], voided cross; mullets in quarters`. Cf. Mack 63; SCBI 18 (Copenhagen), –; North 878; SCBC 1280. Fine, toned, crapes under tone on reverse, areas of flat strike making moneyer and mint only conjectural.

Barring an exact die match, the stylistic affinities of the Mack coin suggest that the mint of this coin is Pevensey, and the moneyer is Alwine.
