2 Crowns - Charles III Heroes of Telemark

The Heroes of Telemark operation — formally Operation Gunnerside — was executed in February 1943 by Norwegian Special Operations Executive agents who sabotaged the Vemork heavy water production facility in German-occupied Norway. The attack set back the German nuclear program by an estimated two years, though historians continue to debate the precise impact. Gibraltar has issued commemorative gold coinage under Crown authority for decades, often targeting the collector market with event and anniversary themes.

At .375 fineness, this is 9-carat gold — the minimum legal threshold for gold coinage in the UK and its territories.
