French Bronze coin dated 1637 [opgelost]

Another detected coin dated1637 bronze and 20 mm diameter, 1 mm thick the reverse is easier to see the obverse isn't very clear due to a limescale crust that forms on the coins in this very hard water area.
What is it and does it have any value?
I have another similar which I think the date is 1658 . I also have a slightly smaller coin like this but I can't see any detail because of the same reason. 😖🙂

The reverse of the coin.
Thank you for looking 👍

I put 1637 and Fleur-de-lis in the search and there is only this one result ...

I have seen quite a few of these lately.

It's a double tournois 1637 L. Compare with these search results.

Citeer: "Camerinvs"​It's a double tournois 1637 L. Compare with these search results.

​All these in your list have only three fleur-de-lis on the reverse, except one, the one from ZackUK's search result (https://en.numista.com/catalogue/pieces54220.html)

Ok so this coin is the one that zacuk found.
So, is of any value at all? or is the state too bad?
I did put a torch to the right of it when I photographed it so you could read it easily with the raised picture and dates but it has made it look a lot lighter than it actually is.
I'd really like to know the answer to this one as I have 10 from this era.
Thanks again 🙂👍

Oh! ─ I didn't see Zac's link was leading straight to the right type. Well done.

I was on my iPad, which I don't find great for sites like Numista which don't come with an "app" version...
