Well, the portrait looks a little cartoonish in my opinion but if this coin fills a gap in your collection, great! Christian
I think, had I been Friedrich Wilhelm Der Grosse....I would have fired the Mintmaster and his gang and offered a bonus to entice some real experts to do a better job. The portraits on Brandenberg-Preussen coinage only got better after 1800. The Holy Roman Empire seemed to have the best mintmasters/ engravers 1500-1800.
