French Coin Found in Texas

I found this coin on property that my inlaws own in east Texas.Its French but we have no idea how it wound up here.Anyway,as you can see the condition isn't very good but it was a thrill to find. And I use a Bounty Hunter Sharpshooter with the 10" coil in all metal mode.You would be amazed at how much stuff ya miss when you use the discriminator on your metal detectors.I did for years and by accident put the thing in all metal on a hunt one day and found more "stuff" than I ever had before.Yeah,there was some junk too but it is still alot more fun finding anything than nothing(in my opinion).
Should anybody out there know anything about this coin let me hear from you....Thanks

I am no expert in coins, but I just bought my first detector (Lone Star Bountyhunter).  I think I will use your advice on the setting and avoid the discriminator.  What do you put the sensitivity on?

Thanks for any reply. And, by the way, my parents live in Yantis.

I always set the sensitivity to high.My model you have to hit the ground balance button every few minutes but I find alot of trash but also the good stuff.
