5 Thalers - Frederick Ulrich Löser

Frederick Ulrich's reign over Brunswick-Wolfenbüttel was, by most measures, a disaster — marked by administrative incompetence, constant conflict with the territorial estates, and the catastrophic intrusion of the Thirty Years' War into Lower Saxony. This 5-thaler Löser was struck in 1620, the same year the war's first phase was reshaping alliances across the Empire. Lösers of this denomination were never intended as circulating currency; they functioned as prestige gifts, diplomatic tokens, and display pieces for the ducal court.

The Brunswick mint's output of large-format silver multiples during this period drew on the Rammelsberg and Harz mountain silver supply, still productive in the early seventeenth century before wartime disruption choked regional mining.
