5 Mark New Palace of Potsdam

Issued to mark the 225th anniversary of the New Palace at Sanssouci, this was one of a long series of GDR commemorative five-mark pieces that served double duty as both circulation coinage and quiet cultural propaganda — the regime consistently favored Prussian architectural heritage as a way of claiming historical legitimacy over a territory it had largely inherited by geography. The New Palace itself was Frederick the Great's deliberate act of defiance after the Seven Years' War, built not because he wanted it but to demonstrate that Prussia's treasury had survived the conflict.
