Douzain - Mary

Dombes operated as a semi-autonomous principality in the Ain region under the House of Montpensier, and by 1613 it was governed by Marie de Montpensier — the "Mary" of this denomination's name. The principality retained the right to strike its own coinage under royal tolerance, a privilege increasingly rare as the French crown consolidated monetary authority through the seventeenth century. Dombes' mint at Trévoux was among the last active feudal mints in France, not finally suppressed until 1762.

The billon douzain was the workhorse of petty feudal commerce. The Divo reference spread across four numbers suggests minor die variations across the issue's run rather than distinct emission years.
