Sterling - John I Bust type, Limburg in title

John I of Brabant issued these sterlings during a period when the duchy was deeply embedded in the commercial networks of the Low Countries, and English sterling penny types were being imitated across the region precisely because merchants trusted their silver content more than local issues. The Limburg title reflects John's acquisition of that duchy in 1288 following his victory at the Battle of Worringen — one of the largest pitched battles of the medieval period in the Low Countries, settling the War of the Limburg Succession in Brabant's favor.

Worringen was fought on June 5, 1288.
