Artificial Intelligence looks to a future that is both fascinating and unforeseeable. The coin’s reverse features the outline of a head that symbolises our ignorance about the future functioning of humanoid ‘super intelligence’. The fact is that we do not know what will happen when artificial intelligence has worked out how to improve itself and no longer relies on us. Will it imprison us or will it set us free? Only time will tell, but in the meantime the thought-provoking 2019 addition to our bestselling Silver Niobium series uses its electric-blue niobium core and silver outer ring to beautifully visualise our uncertainty.

Knights’ Tales is a fascinating five-coin series in which we travel back in time to a bygone age that was notorious for being bloody and brutal. But the Middle Ages was also the age of chivalry, when high-born warriors known as knights rode into battle on horseback dressed in full armour. The code of chivalry was a combination of the warrior ethos, piety, nobility and gallantry. To his loyal subjects, Maximilian I, to whom the first coin in the series is dedicated, embodied these values. The year 2019 is the 500th anniversary of the death of the Holy Roman Emperor and Archduke of Austria.
