1⁄12 Ecu - Honore II

Honoré II secured formal recognition of Monaco's sovereignty from Louis XIII in 1641 through the Treaty of Péronne, ending decades of Spanish suzerainty. These small silver pieces, struck within a decade of that political realignment, were among the first coins issued under genuinely independent Monégasque authority — the right to mint had been explicitly confirmed as part of that treaty's terms.

The Gadoury reference splits this type across two varieties, MC13 and MC14, distinguished by minor die differences that remain the subject of ongoing collector debate regarding precise date attribution within the 1650–1653 window.
