50 Kroner

This is a wartime note printed under German occupation. Norges Banks Seddeltrykkeri had continued operating in Oslo after the April 1940 invasion, and the occupying authorities allowed — indeed required — the bank to maintain note production, using the machinery and staff of Norway's own national printer to fund the occupation's administrative costs through controlled monetary expansion. The 1944 date places this note in the final year of that arrangement.

The series saw significant post-liberation scrutiny. After May 1945, the Norwegian government implemented a currency registration program requiring citizens to declare all banknotes held, partly to identify those who had profited under the occupation. Notes that passed through that process were stamped or overstamped before re-entering circulation.
