1⁄12 Ecu - Honore II

Honoré II secured formal recognition of Monegasque sovereignty from Louis XIII in 1641 — the Treaty of Péronne — ending decades of Spanish suzerainty and making him the first to hold the title of Prince of Monaco rather than merely Lord. This coin was struck just over a decade into that new political reality, during a period when Monaco was actively asserting its identity as an independent principality under French protection. The 1⁄12 écu denomination places it within the French monetary orbit almost by design.

Gad#MC14 is genuinely scarce. Monaco's output throughout the seventeenth century was modest by any measure, and attrition has been severe.
