5 Ducats - Johann Christian and Georg Rudolf Reichenstein

Johann Christian and Georg Rudolf ruled Liegnitz-Brieg jointly following the death of their father Joachim Friedrich in 1602, a co-rulership arrangement that was itself a product of the fragmented inheritance customs governing Silesian duchies under Habsburgs suzerainty. The year 1610 places this striking squarely within the decade before the Bohemian revolt that would engulf Silesia in the Thirty Years' War, making multi-ducat presentation pieces like this one a form of dynastic self-assertion at a politically anxious moment.

Five-ducat pieces from Liegnitz-Brieg are known in very small numbers; the FuS reference alone suggests a sparse survival record for this specific denomination and co-regency pairing.
