1 Crown - Elizabeth II English Electric Lightning

Gibraltar has issued commemorative crowns prolifically since the 1970s, targeting the collector market with a breadth of subjects that has little to do with the territory's own history. The English Electric Lightning falls squarely into that category — an aircraft that never operated from Gibraltar but was the RAF's primary interceptor from the late 1950s through the 1980s, the only British-designed aircraft capable of exceeding Mach 2 in level flight.

The Lightning's unusual stacked-engine configuration, with one Rolls-Royce Avon mounted directly above the other, was a direct consequence of early aerodynamic research conducted at Warton under W.E.W. Petter.
