10 Kroner - Margrethe II 4th portrait, Northern Light

The "Northern Light" reverse was part of Denmark's ongoing themed circulation series launched in the 2000s, which periodically refreshed 10-krone designs while retaining Margrethe II's fourth portrait — itself introduced in 2001 and sculpted by Gunvor Tvilling. The fourth portrait replaced the third after the Queen's 60th birthday, a standard practice for Danish coinage that tracks the monarch's age across decades of issue.

Aluminium bronze was adopted for the 10-krone denomination in 1989, chosen partly to distinguish it from the bimetallic experiments then circulating elsewhere in Europe.
