Gold Ecu - Mary

Dombes was a sovereign principality straddling the Saône floodplain north of Lyon, and in 1618 its ruler was Marie de Bourbon, who had held the title since 1608 following the death of her father. French feudal principalities retained the right to strike gold coinage well into the seventeenth century, though that right was increasingly contested by the Paris mint establishment. Dombes exercised it stubbornly.

The principality's coinage was abolished entirely in 1762 when Louis XV incorporated Dombes into the French crown following the death of the last Bourbon-Condé prince to hold it.
