The 1350–64 French Mutin d’Or is one of the most intriguing coins from medieval Europe, valued not merely due to its scarcity but for the historical turbulence it represents. Minted during the reign of King John II of France, this gold coin arose amid the devastating onset of the Hundred Years’ War. The English had just won a decisive victory at the Battle of Poitiers in 1356, アンティークコイン and John II fell into English custody. The royal coffers were emptied, and the kingdom faced not only military defeat but also economic instability. Amid this chaos, the Mutin d’Or was hastily authorized.

The term Mutin d’Or signifies "rebellious gold", a allusion to its deeply disputed creation. Struck in desperation to pay the exorbitant sum the English demanded for the king’s liberation. Designed to meet the highest gold content standards, but due to the urgency and lack of resources, a significant portion contained impurities. Many fell short of the stated fineness, and others were struck with poor craftsmanship. The deception ignited protests in Paris, Lyon, and beyond. Vendors and lenders dismissed them as unreliable currency, and "Mutin" became a rallying cry for public outrage against royal mismanagement.

Despite its troubled start, the Mutin d’Or emerged as an emblem of endurance. When the crown reasserted fiscal discipline and reformed minting practices, the coin gave way to rigorously regulated currency. But its legacy endured. Historians now view the Mutin d’Or as a critical turning point in French monetary policy. It revealed the perils of fiat currency unsupported by gold, and compelled future monarchs to enforce strict minting protocols.

Each remaining piece is a treasured artifact for both private collectors and public collections. Each coin embodies a turning point when France fought to survive. Struggling to maintain order through desperate measures and imperfect solutions. The Mutin d’Or reminds us that money is more than metal and design. It reveals how currency mirrors the soul of a society under siege.
