5 Pounds - Elizabeth II First Supersonic Flight of Concorde

Concorde's first supersonic flight took place on October 1, 1969, piloted by André Turcat over southern France — a full four years before the aircraft entered commercial service. Gibraltar's embrace of Concorde commemoratives is a product of the island's long-running strategy of issuing collector silver on British prestige subjects, a market largely sustained by the Crown Dependencies in the early 2000s. KM#1321 is one of several Gibraltar issues on aviation themes from this period, all sharing the same 28.28g sterling blank used across dozens of Commonwealth commemorative programs simultaneously.
