1 Ducat - Christian

Christian of Brandenburg-Bayreuth ruled from 1603 until his death in 1655, but the dating range on these ducats — 1609 to 1632 — spans the entirety of the Thirty Years' War's opening phases. Brandenburg-Bayreuth sat squarely in the war's path, and the margraviate changed military occupation repeatedly. Coinage continued partly from necessity, partly to assert sovereignty during periods of acute instability.

The .986 fineness conforms to the ducat standard established by the Holy Roman Empire, maintained with remarkable consistency across German states even as silver coinage was being systematically debased. Fr#368 cross-references confirm this as a recognized type in Friedberg's gold census.
