Roquelay Desaide button

My first time at Numista  Just acquired 5 of these buttons.  30 mm   12 grams  Info please.   Thank you !

There were so many button manufacturers in Paris in the 18th-19th centuries, that “Paris Back” is an entire category among button collectors.

I have loads of them. 

The back marks are as interesting as the front designs.

Here are a few relevant internet resources, googled up for you
