1 Thaler - Rudolph August and Anthony Ulrich

Brunswick-Wolfenbüttel operated under dual rulership from 1685, when Anthony Ulrich joined his elder brother Rudolph August as co-regent — an arrangement born less from political necessity than from Rudolph August's genuine preference for delegating governance. The elder brother retained nominal seniority but effectively withdrew from active rule, leaving Anthony Ulrich, an accomplished poet and novelist, to manage both the court and its affairs. Joint-reign thalers of this type were struck across multiple years through the Zellerfeld mint, and the series spans enough dies and minor variants that Welter's cataloguing remains the essential reference for separating them.
