Need help identifying a very worn coin [opgelost]

Hello, 

My grandfather gave me some old coins. He is a former banker so he collected quite a bit. I have been able to identify most using Numista, but this coin is very worn and I can only make out a few details. Any help is appreciated.

The coin is approximately 1 inch (2.45 cm) in diameter and weighs approximately 0.17 oz (5 grams). It is nonmagnetic and mainly brown, so its composition could be copper

Side 1: I think I can make out an upper case “L” with serif.

Side 2: There seems to be a circle in the middle with four crowns, possibly with lilies atop, around it.

If anyone can help, it would be most appreciated.

Thanks,

 I have similarly worn one myself, and another member helped to identify it. 

Cannot remember what it is, but will have a look … 

 Here is mine … 

 Will look for the topic I put it in; or the link … 

 I right-clicked on my second picture 

 and chose ‘Search image with Google’ which appeared on screen right 

 which down the results was that French 6 Deniers Louis XIV coin.

I have been looking for what the four-leaf shape is called. I've tried shamrock, but nothing yet.

EDIT: Google Lens search found it!

I think we found it!

 Yes, shame can not see any lettering. Cropped and rotated 

 On that link I added earlier there are three Mints. It shows & in the middle 

on that page, and the other two are H or N letters - yours looks like H so is La Rochelle.
