1 Schilling - John IV Alchimysta

John IV ruled Brandenburg-Bayreuth from 1437 until his death in 1457, earning the epithet "Alchimysta" — the Alchemist — from contemporary chroniclers who noted his obsessive, and reportedly ruinous, pursuit of transmutation. Whether the nickname reflected genuine laboratory work or merely fiscal desperation is debated, but the margraviate's finances were chronically strained throughout his tenure. The irony of an alchemist unable to conjure solvency while overseeing silver coinage was not lost on later historians.

Schr#264 places this schilling within a documented sequence for the Franconian line. The long date range reflects the absence of annual die changes rather than extended production certainty.
