10 Euros - Coin of History Guillaume the Conqueror

This piece belongs to Monnaie de Paris' long-running "Coin of History" commemorative series, which has recycled the same billon specification across dozens of issues — a format kept affordable precisely because the target buyer is a collector of the theme, not the metal. Guillaume himself needs little introduction, but 1066 is only half the story: his claim rested on an oath allegedly sworn by Harold Godwinson at Bayeux, the disputed nature of which gave the invasion a legal pretext the Norman chroniclers were careful to preserve.

The .333 fineness dates this alloy tradition to French token coinage rather than any silver monetary standard.
