French Coin has 1840 or 1830 help identify

Hi guys!

Need your help again.
Google usualy helps me but I feel trapped with this one.
I think it's a commemorative coin from France - can you point me with a link or name .. or maybe value ?



Tkx a lot !

  It can not be a coin, as there is no denomination. It is a medallion issued in 1840 to commemorate the 10-year anniversary since the 1830 dates.  

 You may be helped more on the French version of this forum ...

Tkx for the tip !

   I do not know what you typed in Google, but on there I typed
1830 "AUX HEROS MORTS EN DEFENDANT LES LOIS"
and this was the first result ...
