Hello paschka, here is, I believe, what you're looking for : https://www.cgb.fr/corporations-serruriers-emission-de-1777-spl,fjt_08001,a.html But don't ask me more ! I know nothing about tokens... The seller commented : "in Rome, the groups of craftsmen already existed: forming a college under the protection of a deity, with a common house and fund". What I learned about late roman laws, is that, in order to prevent the flight of corporations, heredity was imposed ! (M. Humbert (University professor, Paris II), Institutions politiques et sociales de l'Antiquité, Paris 1989, p.484).
I know nothing about these, but it's obviously Louis XVI so the late 18th century. I'd start with that.
