Florin - Johan I von Luxemburg

Johann von Luxemburg, known as John the Blind, struck florins in close imitation of the Florentine florin, which had by the 1320s become the dominant gold trade coin across Europe. Bohemia's adoption of the type was pragmatic: the Florentine standard carried instant credibility in international markets, and John needed that credibility to finance relentless military campaigns across Poland, Silesia, and northern Italy. He spent more time campaigning abroad than governing at home.

John died at Crécy in 1346, fighting for France against the English despite being almost entirely blind — his horse reportedly tied to those of his knights so he could charge into battle. The Don #816 reference places this among the documented Bohemian florins struck before that campaign ended his reign.
