The copper version of your jeton is described in CGB's `Jetons XXII' which rather strangely is not on their web site
http://www.cgb.fr.
I'm in process of moving location so my reference books are not currently available to me, so I can't give you any more info than is contained in Jetons XXII.
The bust is by Jaques Nilis (N below the bust) is of King Louis XIV of France. CGB believe the bust type to be rare, but frankly I have seen numerous jetons bearing that bust design.
The reverse is the allegorical figure of `La Ville de Paris' (the city of Paris). Paris is seated, leaning on her shield (coat of arms of Paris) holding a platter laden with fruit and a palm (symbolising peace and prosperity?). In the distance is a view of paris city including Notre Dame, all of which is beneath a radiant sun. The `radiant sun' is the sybolic representation of Louis XIV who was also known as `the sun king'. The legend very roughly translates as "it realizes (benefits from) the effectiveness of its will". All very symbolic, as most jetons are. I presume that this particular jeton was issued to demonstrate honour and allegiance to the king. CGB assign it as F.3420. That is, as catalogued by Feuardent.
Your jeton is in a very collectable condition. CGb's example is in much the same condition and they were asking 35 euro for theirs. A bit optimistic perhaps for a copper example, but there you have it.
Hope that helps
