1 Escalin - Louise Marguerite

Château-Regnault was a tiny principality on the Meuse in the Ardennes, and its right to strike coin was perpetually contested by the French crown. Louise Marguerite de Bourbon-Conti — widow of François de Bourbon, Prince of Conti — held the territory and exercised that minting privilege aggressively, producing a range of denominations that Paris considered an irritant. The French monarchy's ongoing campaign to suppress seigneurial coinage rights makes any surviving piece from this mint a direct artifact of that jurisdictional friction.

The escalin was a denomination borrowed from the Spanish Netherlands, which tells you something about where this border principality oriented its commercial relationships.
