Well, apparently, not many of the Sedan types actually say Sedan on them, and this one has a clear large tower. So it's probably this type (Principality of Sedan, 1634-38).
Chances are, the specific date is visible in hand, but I can't pick it out from the photo, unfortunately.
I also have a Double de Sedan coin, ironically - but mine is the small-tower type (1638-42, Numista 54057).
