Double Tournois - Francis 8th type

Château-Regnault was a tiny principality on the Meuse in the Ardennes, and its right to strike copper coinage was perpetually contested by the French crown. The Double Tournois issues produced under this authority during the early seventeenth century closely mimicked royal French types — deliberately so, as the principality's monetary legitimacy depended on appearing indistinguishable from sanctioned coinage. French authorities periodically moved to suppress such feudal issues, with limited success.

The "Francis 8th type" designation refers to Françoise de Bourbon-Condé's husband François de Bourbon, Prince of Conti, under whose authority the fief operated.
