20 Pounds - Elizabeth II Little Ships of Dunkirk

The "Little Ships" evacuation of May–June 1940 saw roughly 700 civilian vessels — fishing boats, pleasure cruisers, Thames ferries — cross the Channel to lift over 338,000 Allied troops off the beaches at Dunkirk. Gibraltar's connection to the event is oblique at best; the territory has become a prolific issuer of commemorative silver for the collector market, and this coin fits squarely within that commercial output rather than any direct historical tie.

The 7.77g weight places it in the fractional "quarter-ounce" format favored by modern commemorative programs targeting entry-level silver buyers.
