Weight: 3.77 g. Ex-Thomas Numismatics, 18 June 2025, via their MA-Shops storefront. Prior provenance to the Beaussant Lefèvre – Thierry Parsy (Hundred Years' War hoard) sale, 30 June 2009, Lot 231. This coin is a gold Ecu d'or of Charles VI of France, who was known variously as "the Beloved" and "the Mad". It was part of a treasure hoard of 2,665 gold coins found in terracotta and metal pots at Lucerne Abbey in Normandy, France, where it had been deposited during the protracted Hundred Years' War between France and England. This treasure, unearthed between 1968 and 1970, is often referred to as The Hundred Years' War Hoard. The auctioning of the treasure in the early 21st century helped to restore the abbey. 402094
Charles VI, who signed "the shameful treaty of Troyes" (as old French history textbooks used to call it). This man was completely nuts, but history taught us it is not much of a problem for being head of state. C. 1420, one day or one night, burglars broke into the Louvre. It wasn't yet the museum we know, it was a medieval fortress in the outskirts of Paris, but it already kept the precious regalia. The burglars stole the parade helmet of Charles VI, made of gilded copper with enamel. They broke it in 150 pieces to remove the gold plating, and discarded the pieces in the castle moat, where archaeologists found it in the 1980s. Because of the inscribed motto "EN BIEN", this helmet was positively identified as the helmet of Charles VI. The sad thing is that the Louvre's security didn't improve that much since the early 15th century...
