Does it have another side or is that the best? Despite its probable age, another for the silver scrap bag methinks.
Need better picture, the other side as well would be nice, a size reference would also be helpful, but it looks like British silver, I think William III. no idea what denomination without a size reference.
Like everyone else, I would say French or British (though I lean more towards British), but such a small photo of one side of such a worn coin is difficult to identify.
