⅙ Plaque - Jean the Blind Luxembourg-Bar Convention

Jean the Blind — John I of Luxembourg, King of Bohemia — struck these small silver pieces under the monetary convention he maintained with the County of Bar, a cooperative arrangement that allowed both territories to produce compatible coinage for regional trade. John died at Crécy in 1346, famously ordering his knights to tie their horses to his so he could strike at least one blow against the English despite being completely blind. He never returned from the battle.

The Bar convention issues are among the more technically obscure of his Luxembourg coinages, sitting outside the better-documented Bohemian royal series and consequently underrepresented in major collections.
