50 Euros Golden Fleece

The Golden Fleece order was founded in 1430 by Philip the Good, Duke of Burgundy, partly as a political tool to bind the Flemish nobility to his rule and partly in deliberate rivalry with the English Order of the Garter. Its continued prestige across six centuries — passing through Habsburg and then Spanish and Austrian dynastic hands — made it one of the few chivalric orders to survive intact from the medieval period into modern sovereign courts. France's connection is oblique enough that this Monnaie de Paris issue sits in an awkward historical space, drawing on classical myth rather than any direct French institutional lineage.
