5 Rigsdaler Courant - Christian VII Backprint on Danish note, blue paper

Kurantbanken — formally the Banco di Giro, later reorganized and renamed — was already in serious institutional difficulty by 1800, caught between the demands of wartime finance and chronic over-issuance that had been eroding public confidence in Danish paper money for decades. The blue paper used for this denomination was a deliberate anti-counterfeiting measure, one of the more visible security choices in an otherwise modest production run handled domestically in Copenhagen.

The bank collapsed in 1813 under the weight of state borrowing during the Napoleonic Wars, triggering a formal bankruptcy and currency reform. Notes from the final years before that crisis are correspondingly scarcer than their earlier counterparts.
