Need help identifying coin found in Menorca

Hi all,  found this today in the garden of villa we are staying in in sunny Menorca… I think it may be Spanish… Charles III, but he's facing the wrong way….  Back of the coin is a bit toasted, but I think that may be a castle, top left… part of a castile and lyon coat of arms…. Of course, the Brits held Menorca for a large part of the i8th century, so could be a George halfpenny maybe?  Its roughly 25mm wide…

Something like that…

N#4944

Yes… thank you… it looks indeed like it's a   Louis XVI ½ Sol. The villa I'm staying in is just a few kilometres from the town of Sant Lluis,   named after the French king and founded during France's short occupation a few decades before this coin was minted… so looks like French coins were being used locally, after the Brits took over again…
