Denier - Louis VI Mantes, 1er type

Louis VI ruled as the first Capetian king to exercise genuine administrative control over the Île-de-France, spending much of his reign in bitter armed conflict with local barons who had effectively privatized the roads and bridges around Paris. The Mantes mint was one of several he worked to bring under tighter royal authority during this consolidation — coinage rights having been widely usurped by regional lords in the preceding generations.

The Dy royales references 111–113 reflect recognized die or type variants within this emission, suggesting meaningful production volume across the nearly three-decade span.
