1 Pfennig - Emmerick Joseph of Breidbach of Bürresheim

Emmerick Joseph von Breidbach-Bürresheim served as Archbishop-Elector of Mainz from 1763 until his death in 1774, administering one of the Holy Roman Empire's most politically consequential ecclesiastical territories. Erfurt, though geographically distant from Mainz itself, remained under archiepiscopal jurisdiction as a subject city — a persistent source of friction with surrounding Ernestine Saxony that predated this coinage by centuries.

By 1771, copper pfennig coinage from Erfurt was largely a matter of local necessity, filling the small-denomination gap that silver issues left unaddressed. Leitzmann 741 is specific to this mint and reign combination.
