1 Thaler - Christian IV

Palatinate-Birkenfeld-Zweibrücken was one of the smaller Wittelsbacher territorial fragments, separated from the main Palatinate line through generations of inheritance division. Christian IV ruled from 1735 until his death in 1775, and his thalers were struck under the minting rights still nominally held by these petty Rhenish duchies — rights increasingly difficult to justify economically as the mid-century wars drained the Holy Roman Empire's smaller states. The Seven Years' War was in full progress in 1760, disrupting trade networks that gave thaler-sized silver any practical velocity.

Davenport's cataloguing under the German Talers II series places this among a thinly documented run with low surviving populations across all grades.
