1 Thaler - Albert II Siege of Schweinfurt

Albert II Alcibiades — the nickname earned for his reckless military adventurism — struck this thaler during his siege of the Free Imperial City of Schweinfurt in 1553, one of the final acts of the Second Margrave War. He had spent years plundering ecclesiastical and secular territories across Franconia, making enemies of virtually every neighboring power simultaneously. The siege itself ended badly; a coalition of Franconian princes and the Duke of Alba's Imperial forces crushed Alcibiades militarily, and he died an exile in Pforzheim in 1557, his territories forfeit.

Siege coinages of this type were struck from whatever silver was available locally, which accounts for the weight inconsistencies seen across the MB#54 population.
