1 Øre Grønlands Administration, overprint

Greenland was effectively cut off from Denmark after the German occupation in April 1940, leaving the island's colonial administration to improvise its own monetary arrangements. These cardboard emergency pieces — sometimes classified as notgeld rather than true banknotes — were authorized by the Danish governor Henrik Kauffmann, who simultaneously signed an agreement with the United States granting American military access to the island. That political rupture with occupied Copenhagen made Greenland's wartime administration uniquely autonomous for its brief duration.

The cardboard substrate is prone to moisture damage given Greenland's climate, and surviving pieces in clean condition are proportionally rarer than their modest face value suggests.
