2 Sovereigns - Elizabeth II 75th Anniversary D-Day

Alderney's particular claim on D-Day commemoratives is geographical — the island sits roughly 50 miles from the Normandy beaches and was itself under German occupation from 1940 until liberation in May 1945, making it the only part of the British Isles to have been occupied. That history gives these issues more grounding than the typical commemorative gold, even if the denomination is nominally tied to the Crown Dependencies' ceremonial coinage structure rather than anything circulating.
