Greenland, 50 Øre (1874), first year of issue for the Greenlandic krone. The uniface note (valued at half a krone) was issued in Denmark for use in Greenland. The note depicts the royal monogram of Christian IX of Denmark on the left and a small crowned polar bear on the right. More recent issues (just shy of being free of copyright) depict a larger polar bear.
