1 Øre - Frederik IX

Denmark's wartime zinc coinage, introduced under German occupation in the early 1940s, was never retired after liberation. The Royal Danish Mint simply continued striking in zinc through the postwar decades — a pragmatic concession to metal economics rather than any deliberate policy. Copper remained expensive and strategically prioritized elsewhere in European reconstruction.

The series ran until Denmark decimalized and restructured its coinage in 1972, at which point the 1-øre denomination was abolished entirely.
