10 Pounds - Queen Elizabeth II D-Day 75th Anniversary

The 75th anniversary of Operation Overlord prompted a wave of commemorative issues across British Crown Dependencies, and Guernsey's geographic position made its participation more than ceremonial — the island had been under German occupation since July 1940 and remained so until liberation on 9 May 1945, nearly a full year after the Normandy landings it now commemorates. Guernsey was not liberated by D-Day; it was liberated despite the Allies choosing to bypass the Channel Islands entirely, leaving the garrison to surrender only after Germany's general capitulation.

The 5-ounce format places this squarely in the modern bullion-collectible category that the Royal Mint and its Crown Dependency equivalents leaned into heavily through the late 2010s.
