My newest purchase.
1380-1422 charles vi french ecu'or.

It is nicely centered and a nice strike with minimum wear.
Hard to photograph through the slab but it's nicer in hand.
A little history from the time it was issued:
Charles V1 "The Fool" or "Mad King" (1380-1422)
"The king: Charles came to the throne in 1380, but experienced mental illness in 1392 which plagued him throughout his life. This set the stage for conflict among his uncles and other French nobility, which weakened the position of the king in the war with England. A Burgundian alliance with England led to the fall of Paris in 1418, and subsequent occupation by the English.
The times: the battle of Agincourt( 1415) was a success for English bowmen over French knights. This led to the Treaty of Troyes in 1420, which identified Henri V of England as successor to the French throne on Charles' death. This period is the French nadir in the 100 years war, with the crown withdrawn from Pairs and settled in the south at Bourges. Henri V married Charles' daughter Catherine. Their son was Henri VI of England."
