Faster than Sound, the fourth and final coin in the Reaching for the Sky series, is dedicated to the undisputed star of commercial air travel, the supersonic airliner Concorde. The most iconic and glamorous airliner to ever grace the skies, Concorde was not only a triumph of engineering but, with its delta-wings and slightly bent nose, also a design classic. In service from 1976 to 2003, Concorde captured the public imagination like no other civil aircraft before or since.

Given just how tough the armoured ankylosaurus magniventris was, it is not surprising that this massive herbivore was one of the last large non-avian dinosaurs to roam the earth. Looking like a four-legged tank with a broad torso covered in humps, spines and protected by a bone-plated corset, not to mention horns pointing backwards from the back of its head, ankylosaurus magniventris is brought to life in vivid detail on the fourth coloured coin in the Supersaurs series.
