The 1350–64 French Mutin d’Or is among the most enigmatic currency pieces of the Middle Ages, valued not just for its rarity but for the historical turbulence it represents.

Many fell short of the stated fineness, and some bore crude, uneven impressions. The deception ignited protests in Paris, アンティークコイン投資 Lyon, and beyond. Traders rejected them as worthless, and the term mutin came to symbolize both the government’s desperation and the people’s anger.
