1 Pfennig 'Lilienpfennig' - Rupert I

Rupert I ruled the Palatinate for nearly four decades and was among the most politically consequential princes of his generation — he co-founded the University of Heidelberg in 1386 and played a central role in drafting the Golden Bull of 1356, which formalized the electoral college and confirmed the Count Palatine's position as one of seven imperial electors. The "Lilienpfennig" designation derives from the fleur-de-lis motif, a type struck in considerable volume to serve the busy Rhine trade routes passing through Palatinate territory.

The thin fabric and low silver content typical of mid-14th century Rhenish pfennigs mean survivors in any condition above heavily worn are genuinely uncommon.
