Add weight and diameter of the coin. It will help folks to identify. I can say its not slavic and not british. Don’t look french either. So most likely western europe 1600-1700? Try to search catalogs of that period. Start with Spain, Germans, Portugese and if no luck there then check Moravia, Bohemia and Italians. But hopefully once you have weight and size someone here would pin point you exact coin. Good luck.
