Laurence

Thanks for clearing that up. I have no knowledge of the French language. I appreciate all the help, time and knowledge you have shared

Great Dane: Again thanks for weighing in with your thoughts and research. I think you are correct thinking Sr. de Mortier might be the jeweler/artisan who crafted the breast star and that the store was located in the Palais Royal. Still not sure what Mignolet means. Paul Wood commented that it looked like 3rd quarter 19th century. Wasn't this award mainly for Poland and Russia? Why would it be made in France. Also do you think it is still collectable because of the damage.

Thanks Paul for your comment. Does anyone know what SRDE means, mortier means mortar but I can't figure out the SRDE (small R with a dot under it). And why does it have an address in Paris of the used to be palace?

Great Dane, thanks for the information. Though I would add a full picture of the backside.

I have a Saint Stanislaus breast star that I cannot identify. The only mark on the back in an oval says "MIGNOLET SRDE (R is small with a dot under it) MORTIER PALAIS ROYAL N.34 PARIS". The star is 86.6mm across. The original pin is missing which probably had the maker's name on it. Someone way back soldered a different attachment so it could be worn. Also it has some damage to one of the star points. There is a piece of metal that was used to attach the broken piece but it is missing also. I have searched the internet for many hours with no answers other than the street address on the back is a royal palace in Paris.
