Yes. Polish. Augustus III (of Saxony) King of Poland from 1733 to 1763. As to the coin. Is this some kind of competition you are holding or something? If yes...what's the prize. If not.... you should know better by now than to withold information that can assist with identification. For example what size is it? Does it have a reverse and if so what has it got on it? If it is about the size of a modern UK penny /US cent then it is a `solidus' dated somewhere between 1749 and 1755. Ian
