Not French but Austrian Netherlands. it is a Kronenthaler or a fraction of a Kronenthaler, depending on size. Here is a link to what it looks like in better shape: https://en.numista.com/catalogue/pieces23333.html
The value in this condition, very worn and with a hole, is unfortunately not more than the silver value, so depending on size something like 5-20 $.
