3 Ducats

Regensburg occupied a peculiar position in the Holy Roman Empire — simultaneously a Free Imperial City and, from 1663 onward, the permanent seat of the Reichstag. That perpetual diet drew diplomats, envoys, and princes in continuous residence, creating sustained demand for high-denomination presentation pieces. Multi-ducat issues like this one functioned as gifts and diplomatic currency as much as coinage.

The twenty-year emission span across 1745–1765 suggests multiple die marriages rather than a single production run, and surviving examples vary noticeably in surface quality and strike pressure.
