Identification please. 1669 on front. Possibly a German state? [επιλυμένο]

 Do you not know about the Search on here? 

At the top of the page is a Coins link. 

Click on that and simply enter the numbers or words you can see on the coin. 

I just put 3 1669 then clicked the blue Search button. 

So even ignoring the diameter for now, yours is in the results …
