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.

A semiaquatic member of the weasel family, thanks to its waterproof fur, aerodynamic shape and stabilising tail, the otter is an excellent swimmer and diver. Having declined greatly in the 20th century, the subject of the eleventh and penultimate coin in the bestselling Colourful Creatures series is now, thankfully, on the road to recovery.

Celebrating the story of manned flight, from the first fearless pioneers to the crowded skies of today, Reaching for the Sky makes four stopovers at the most important stages in the history of air travel. The series takes off in the shape of The Dream of Flight, which illustrates how the fantasy of flight eventually became reality.

The second of our three silver Anniversary coins is sold out and no longer available from the Austrian Mint. Having said that, so that we can offer all three Anniversary coins in a set along with the specially designed Collector Album, we have set aside a small quantity of the coins. This set will be made available from 16 October 2019 to coincide with the issue of Robin Hood, the third and last Anniversary coin. The Album also has space for the five copper coins in the 10 euro Knights’ Tales series.

The three coins celebrating the 825th Anniversary of the Vienna Mint are all linked to the ransom paid to Duke Leopold of Austria for the release of King Richard the Lionheart of England in 1194. They also all contain one ounce of fine silver, the precious metal used to pay the huge ransom, which was partly used to build the stronghold of Wiener Neustadt – the theme of the second coin in this very special series.
