100 Francs - Charlotte John the Blind

John the Blind — King of Bohemia and Count of Luxembourg — died at Crécy in 1346, reportedly charging into battle despite being completely sightless, his reins tied to the horses of his knights. Six centuries later, Luxembourg chose him as the reverse subject for its first large-denomination silver coin issued under Grand Duchess Charlotte's postwar authority. The timing was deliberate: a nation reasserting its identity after Nazi occupation reached back to its most romantically defiant historical figure.

The .835 fineness matches the standard adopted across much of continental Europe in the interwar period and carried through into postwar issues where full silver remained politically viable but economically strained.
