1 Thaler - George William

George William's final years as Elector were among the most catastrophic in Brandenburg's history — his indecision during the Thirty Years' War left his territories repeatedly occupied, looted, and depopulated by both Swedish and Imperial forces. These thalers were struck during that terminal phase of his reign, when the Brandenburg mint was functioning under conditions of near-constant military disruption. That the Marienburg collection catalogued a specimen at all speaks to how few survived institutional dispersal.

The Dav ST#6151 attribution places this within the Stolberg die study, a useful anchor given the overlapping emission dates and the difficulty of pinning individual strikes to a single mint year within the 1635–1639 window.
