1 Heller - Frederick V and Louis I

The Landgraviate of Leuchtenberg was a minor imperial territory in the Upper Palatinate whose ruling family spent much of the fifteenth century in a slow financial decline, progressively selling off jurisdictions to the Wittelsbachs to cover debts. The joint attribution to Frederick V and Louis I reflects a co-regency arrangement common among German dynasties managing contested inheritance — both were sons of Frederick IV and ruled concurrently rather than sequentially.

At 0.25 g, this is essentially the smallest denomination the territory produced, likely struck at the Pfreimd mint.
