10 Kroner - Margrethe II 4th portrait, Sirius

The Sirius Patrol — Slædepatruljen Sirius — has monitored Denmark's claim to northeastern Greenland since 1950, operating dog sleds across some of the most inhospitable terrain on earth. The coin's release coincided with renewed international attention to Arctic sovereignty as climate change began opening previously inaccessible sea routes, making Danish presence in the region a matter of active geopolitical interest rather than ceremonial tradition.

Margrethe II's fourth portrait, by sculptor Bertel Thorvaldsen's institutional successor at the Royal Danish Mint, replaced the third effigy that had appeared on the 10 kroner since the mid-1990s.
