Sterling - John I

John I of Loon issued this sterling during a period when the type had become the dominant trade coin across the Low Countries, with local lords adopting the penny sterling format largely in imitation of English and Flemish prototypes flooding regional markets. The County of Loon, a small ecclesiastical lordship wedged between Liège and Brabant, had limited independent monetary authority and its issues were correspondingly brief and modest in volume.

Lucas 12 and van der Chijs 8#20.9 both treat this as a distinct emission within John I's short coinage period, which ended with his death in 1279.
