Denier - Louis VI Montreuil, 3e type

Louis VI — "the Fat" — spent much of his reign fighting to assert Capetian authority over the robber barons of the Île-de-France, and his coinage reflects that piecemeal consolidation. Montreuil-sur-Mer was among the royal mints he controlled directly, and deniers struck there represent one of the few stable anchors of a monetary system that was otherwise fragmented across dozens of competing feudal issues.

The third type designation distinguishes this from earlier Montreuil emissions by die arrangement — Duplessy's classification separating these issues remains the reference numismatists defer to, catalogued under his Dy royales #116.
