SILVER NIOBIUM (2003-) by the Austrian Mint

A global innovation when launched almost a decade ago, these 25 euro silver niobium coins still combine state-of-the-art numismatic technology and first-rate aesthetic design. First issued in 2003, their silver outer ring and coloured niobium ‘pill’, which is attained by oxidation as opposed to the application of artificial colour, have provided the perfect backdrop for exploringCSP-AUSTRIA-NIOBIUM-BOX suitably technological themes, from astronomy to aviation, robotics to renewable energy and electric light to television.

Although as common as lead and even present in the human body, niobium was only discovered at the beginning of the 19th century. A resistant metal with extremely high chemical stability, it can be rolled and forged at room temperature, which in part explains why niobium is increasingly popular as a component in the manufacture of jewellery. Another of niobium’s facets is that colour does not need to be applied to it. Instead, through ‘anodized oxidation’, the method first applied to coins by the Austrian Mint, a thin oxide layer is produced on the coin surface and subsequent light refraction enables different colours to arise. The resultant effect is quite striking and quite unique.

Equally striking is the quality of artwork on both sides of these coins. The 2012 coin Bionik, has been nominated for an award at the 2014 Coin of the Year awards, the 2011 coin, Robotik, won Best Contemporary Event and the 2008 coin, Fascination Light, won Most Innovative Coin.

We know that many collectors don’t bother looking at Euro coins, but there are some terrific quality series coming from the European mints, and the quality is usually top-notch. The Silver Niobium series definitely fits that description and is well worth a good look. They come packaged in the Austrian Mint’s usual little red box, which are small, neat and appreciated by those with collections that can do without huge amounts of packaging.

Mintages have settled at 65,000, and they all seem to sell out. A recent boost has given the series a real kick. Since the 2014 coin there has been the use of two-colours for the niobium pill, the Cosmology and Time coins in particular being very appealing pieces. An attractive, unusual collection that’s reasonably priced. We’d like to see the process applied to a coin series with more worldwide appeal as well, although the Royal Canadian Mint has also used it on a few issues.


First, the bad news: it’s getting hotter. The good news is that by acting in an environmentally friendly way, each and every one of us can play a role in limiting the temperature increase. Global Heating, the 2023 edition of our bestselling Silver Niobium coin, is a timely reminder that we need to act before it is too late.

The temperature increase caused by humans since 1850 has already exceeded the 1 °C mark. Not that this is a new insight. Back in 2015, the Paris Agreement set the long-term goal of limiting the temperature increase to 1.5 °C and this was reaffirmed at the UN Climate Change Conference in 2021. But the current measures for reducing greenhouse gas emissions do not go far enough for that goal to be achieved. It is now feared that a temperature increase of more than 3 °C could occur by 2100, which would have catastrophic consequences for both humans and the natural world.

If, by 2030, global CO2 emissions could be reduced by 45 per cent, we would be well on the way to preventing that increase. But time is running out, and we are already starting to see the disastrous effects of global heating. Extreme weather events, melting glaciers and changes in climate patterns are becoming increasingly common. Reducing energy consumption and the sustainable use of natural resources are important steps in combating such developments. Every ton of greenhouse gases that we do not produce could help avert catastrophe.

Depicted inside the blue and gold niobium core of the coin’s obverse, a thermometer forms part of a clock that symbolises that time is running out. To its left is a globe, on which it says +1.5 °C. A globe also features in the centre of the coin’s reverse, which deals with the economic, ecological and social aspects of sustainability. To the right are the silhouettes of two human faces, in front of them a sea turtle is seen swimming. Due to environmental pollution and global warming, this species is threatened with extinction.

What if there really is somebody out there? Making contact with aliens would change our whole concept of the universe. Is this really plausible or are such thoughts purely fantasy? Given that we only know a tiny part of the universe, which comprises some 100 billion galaxies, each with 100 billion stars, it is hardly surprising that we continue to ask these questions. The James Webb Space Telescope, the largest, most powerful and complex space telescope ever built and launched into space, is designed to help us find out the answers. The telescope’s improved wavelength coverage and greater sensitivity compared with those of its predecessor, the Hubble, will enable the Webb to look much closer to the beginning of time, when the first stars and galaxies started to form, and fundamentally alter our understanding of the universe. Launched into space on 25 December 2021, since 24 January 2022 the Webb has been successfully unfolded to its operational configuration and successfully entered orbit at its target destination.

The wait for the Webb to detect signs of extraterrestrial life will no doubt be a long one. But in the meantime, one day visitors from another galaxy may drop in to say hello. If they do, will they look down on us or consider us their equals. Whatever the answer, they will have to be from a civilization even more technologically advanced than the James Webb Space Telescope itself.

The Webb is shown in the silver outer ring on the coin’s obverse alongside the famous Drake equation, which is aimed at calculating the probability of extraterrestrial life. The violet niobium core is dominated by an alien holding the earth in its hands like a plaything, symbolising that we may well be defenceless against them should they exist.

In the niobium core of the coin’s reverse, some of the factors that could favour life on other planets are represented: carbon dioxide, methane, oxygen, vegetation and water. In the outer silver ring, the Webb is shown capturing an exoplanet passing in front of a star.

Getting from A to B promises to be both smart and exciting in the future. The plans and concepts illustrated on Smart Mobility, the 2021 edition of the Silver Niobium coin, suggest that mobility will also become healthier. This is because of the health benefits of cycling and using public transport, as well as the subsequent reduction in air and noise pollution in urban areas and the deceleration of global warming.

The appearance of urban spaces will also change dramatically. The basic idea here is the ‘superblock’ concept, in which houses are grouped together as in a garden city and traffic moved to the periphery. Urban areas are thus transformed from parking lots into lively parks where children can effectively play in the street. This will result in more sustainable and environmentally friendly transport solutions. It also implies greater digitization, something that has already led to the invention of self-driving cars and buses and could make air taxis a common sight in the near future.

The coin’s obverse is dominated by a blueprint of an air taxi. The futuristic craft fills the two-tone niobium core and spreads into the silver outer ring so as to underline the visionary nature of this concept. The coin’s reverse underlines the ecologically sustainable, decelerated aspect of smart mobility. The silver outer ring highlights the importance of public transport in the future while the niobium core focuses on the bike and scooter, the most sustainable individual means of mobility. Also in the niobium core, the superblock concept is seen as if through a lens.

The Internet creates infinite possibilities and gives instant explanations by placing the world at our fingertips. But while surfing the net we leave visible traces that businesses use to learn about our individual preferences by analysing the resulting large data sets, meaning that users lose their privacy and autonomy. Big Data, the latest edition in the best-selling Silver Niobium series, highlights the dangers and disadvantages of the digital revolution.

Our lives are digitised to such an extent that it is both virtually impossible to remember how we ever managed during our previous analogue existence and to imagine a world in which hand-held devices do not exist. The Internet opens new possibilities to everyone, but the data collected is usually stored digitally and can be analysed with special software. Thus, before we delve deeper and deeper, we should ask ourselves the following: While I am learning on the Internet, what is the Internet learning about me?

In its niobium core, the obverse of Big Data features a human eye that represents surveillance on the one hand and the biometric method of iris recognition on the other, while the silver outer ring is designed like a camera lens. The reverse of the coin shows people under surveillance, which is recognisable from the 20:20 running time on the left edge of the outer silver ring. In the foreground of the niobium core, one of a number of human silhouettes is peppered with squares that symbolise the personal data collected about that person.

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.

In the form of computer systems able to perform tasks that normally require human intelligence, we have been using artificial intelligence to think for us for several decades. Highly functioning and always available, computers help us go about our daily business in a reliable fashion without us even noticing. The coin’s reverse also symbolically depicts some of the ways in which artificial intelligence does that, in the form of the e-health system, smart machines, processors, digitalisation, data analysis and artificial neural networks. Neural synapses spread from its silver outer ring into the niobium core where they meet a binary code, while the coin’s obverse shows an inverse dynamic: conductor paths extend to the silver outer ring from a processor in a humanoid robot in the electric-blue niobium core.

The footprint of humanity on the Earth is unfortunately a massive one. So big that experts now agree that humanity’s impact on the planet is so profound that it is time to declare a new geologic epoch – the Anthropocene. Examples of this impact are the radioactive elements dispersed across the planet by nuclear testing, plastic pollution and the soot produced by fossil-fuel power stations. These and other adverse effects are illustrated in exquisite detail on Anthropocene, the 2018 edition of our ever-popular Silver Niobium coins.

Beginning at the end of the Ice Age, some 11,700 years ago, the subdivision of the Quaternary geologic period, during which all human civilisation developed, is known as the Holocene. The partly scientific, partly philosophical concept of the Anthropocene is effectively a continuation of the Holocene under a symbolic new name. Different shades of green are used in the coin’s niobium core to illustrate this concept. Humanity and its huge footprint on the planet dominate either side of the coin’s two-tone green niobium core, while humanity’s adverse effects on planet Earth are shown in the silver outer ring of Anthropocene.

The means of transport for this journey is a rather unexpected one  ̶  the butterfly. A shining example is found in the raspberry-red and grass-green niobium centre of the coin’s obverse. But the journey of discovery really begins on the coin’s reverse, where a microscopic view of a butterfly wing is shown at the top of the centre. Moving clockwise we go even deeper with the help of an electron microscope. But that is not the end of the expedition: the bottom half of the coin shows a cell, its structure and even its core. What makes our Silver Niobium coins so special is the fact that their niobium tones arise without the application of colour, purely through light refraction on an extremely thin, transparent oxide layer. Microcosm, like all the other coins in the series,truly glistens with knowledge.

2016-MO-NIOBIUM-TIME-REV

Though hardly the most accurate of chronometers, the sun and moon, which feature on the coin’s reverse, along with an hourglass and watch mechanism, were widely used until the 16th century. It was determined back then that an hour lasts 60 minutes, though time has since been increasingly sub-divided, first into seconds and eventually nanoseconds. This has had the effect of making time ever more precious, with the phrase “time is money“, famously coined by Benjamin Franklin in 1748, being more pertinent today than ever, Standing for lasting value in a fast-moving world, however, the coin shows an old-fashioned clock face in the niobium core and a chronometer in the outer silver ring of its obverse, while the reverse also shows a time spiral and the time in a selection of famous cities.

The theoretical meaning of time may have long been a major subject of debate among philosophers, physicists and religious figures, but the more practical discipline of its measurement has proved to be less of a mystery. Dedicated to the history of chronometry, the latest ingenious addition to the Austrian Mint’s best-selling two-tone silver niobium coins, ‘Time’ uses its two-tone niobium core and outer silver ring to show a selection of timepieces throughout the ages.

Hot on the heals of our trailblazing 2014 coin, featuring two shades of niobium on both sides, comes our stunning 2015 offering, Cosmology. As ever, our innovative Silver Niobium series explores fittingly high-tech themes. This time, Cosmology brilliantly deploys its contrasting blue and yellow niobium hues to bring outer space just a little bit closer to home.

On its obverse, Cosmology features an illustration of the universe in its niobium core, complete with stars, the planet Saturn and its rings, and the Rosetta space probe, the first ever spacecraft to orbit a comet. On the coin’s reverse, the planets in orbit encircle the European Extremely Large Telescope, which is currently under construction by the European Southern Observatory in the Atacama Desert of Chile and is due for completion in 2022. The telescope will enable us to look deeper than ever into the solar system, the galaxy and the universe, concepts illustrated on the coin’s outer silver rings. It may not answer the question: Are we alone in the universe? But it will certainly make a major contribution to the search for extra-terrestrial life.

2014-EVOLUTIONs

Never prepared to rest on its laurels, the Austrian Mint has now made its groundbreaking Silver Niobium series even more innovative. Using two different shades of niobium for the first time, the blue/green 2014 Evolution edition ingeniously illustrates the story of the development of Homo sapiens from other species.

Symbolising the origin of Evolution as a whole, an image of the DNA molecule, also known as deoxyribonucleic acid, graces the coin’s obverse. A debate still continues about who exactly should be credited with decoding the molecule, but Francis Crick, James D. Watson and Maurice Wilkins were awarded the 1962 Nobel Prize in physiology or medicine for their work in this field. The coin’s reverse deals with the history of human development and the diversity of forms of life brought about by evolution, with the design making splendid use of the coin’s outer silver ring and inner niobium pill to do so.

2013-TUNNEL-CONSTRUCTION

One of the most mountainous countries in Europe, Austria has inevitably played a vital role in the development of tunnels. The brilliant ice blue 2013 addition to our innovative 25 euro Silver Niobium series pays homage to Austria’s long and influential contribution to tunnel construction.

Opened in 1848, the vertex tunnel of the Semmering railway was the world’s first alpine tunnel. The ‘New Austrian Tunnelling Method’, which uses the geographical stress of surrounding rock to strengthen a tunnel, was developed from 1957 to 1965 and has since done a great deal to revolutionise tunnel construction around the world. A present-day tunnel boring machine features in the niobium pill of the coin’s obverse, its rotating motion symbolised by three arrows. The obverse’s outer silver ring shows the mountains through which the machine pierces. The coins reverse makes excellent use of the niobium pill to show one of the many road tunnels that pepper Austria’s alpine landscape today, while a tunnel worker uses a pneumatic drill to loosen rock in the silver ring alongside the word “Tunnelbau” (tunnel construction).

2012-BIONIK

As eye-catching, innovative and informative as its predecessors, Bionik, the exquisite purple 2012 addition to our 25 euro Silver Niobium series, pays fitting tribute to how evolution in the natural world acts as a prototype for technology.

Evolutionary pressure typically forces living organisms to become highly optimised and efficient. A prime example is the water-repellent nature of the lotus flower and of shark skin, a phenomenon fundamental in the development of paint. By the same token, the chambered shell of the nautilus has influenced architectural design and the mechanics of bird flight have clearly inspired aviation. All four of these examples feature on the coin’s obverse, while its reverse focuses on the use of bionics in architecture. A radiolarian, the plankton that inspired Spanish modernist architect Antoni Gaudí, is depicted in the foreground, while the reverse’s background shows an interior view of Munich’s Olympic Stadium, the roof of which was based on findings in bionics.

2011-ROBOTIK

Our unique silver niobium technology has again enabled us to produce a unique coin. The 25 euro coin’s two-tone surface provides the perfect background for mint designers Helmut Andexlinger and Thomas Pesendorfer to explore robotics.

Symbolising the fusion between electronics and mechanics, fundamental in robotics, the intricate illustrations on the obverse of this cutting-edge piece feature mechanical cogs and digital binary coding. In its centre a robotic version of Leonardo da Vinci’s Vetruvian man typifies ideal human proportions in the place of a human being, set against the mars-red background of the niobium core. This colour is a reference to the coin’s reverse, which shows a mountainous Martian landscape with a European Space Agency robot exploring the red planet as a star-filled sky and planet Earth shine down from the coin’s silver edge.

Not only one of the key watchwords of the 21st century, sustainability is also one of its biggest challenges. In recognition of this, the outstanding 2010 edition of the Austrian Mint’s popular 25 euro Silver Niobium series features renewable energy and the vital role it plays in a world of dwindling resources.

Inspired by the living, breathing plant process, our engraver Helmut Andexlinger has placed a tree representing all our planet’s vegetation in the shining blue niobium core of the coin’s obverse. The wind blows the tree’s leaves to the ground in a spiral reflecting the life-giving cycle of the four elements – earth, wind, fire and water. All four are also represented in ingenious detail on the coin’s reverse by the contemporary modes of renewable energy used to harness them. Water drives one type of turbine, wind another, the suns rays are captured by solar panels and geothermal heat sources in the earth are recovered in the form of steam.

2009-INTERNATIONAL-YEAR-OF-ASTRONOMY

It is only fitting that the silver niobium coin struck in honour of UNESCO’s International Year of Astronomy 2009 should bear the portrait of Galileo Galilei. A must for all stargazers, this striking 25 euro coin also pays tribute to 400 years of the telescope.

In 1609, mathematician and astronomer Galileo first observed the moon with a telescope. His subsequent drawings of its surface provide the background to his portrait on this marvelous golden yellow silver niobium 25 euro coin’s reverse. The Sterling silver ring around its niobium core shows the development of the telescope spanning from Isaac Newton to present-day radio telescopes. The dark side of the moon was, however, beyond Galileo’s reach. A satellite is shown orbiting it on the obverse of the coin, while the outer silver ring shows planet Earth partly covered by the moon and a stylised sun illuminating the heavens.

2008-FASCINATION-LIGHT

The technology developed by Austrian lighting pioneer Carl Auer von Welsbach is still in use in billions of light bulbs around the world today. The stunning 2008 edition 25 euro silver niobium coin celebrates the 150th anniversary of his birth as well as one of the earliest recognised energy sources – light.

Born in Vienna in 1858, chemist and entrepreneur Carl Auer von Welsbach was one of the key figures in the development of the gas lamp. The obverse of this coin therefore shows, in exquisite detail, such a lamp being lit outside Vienna’s neo-gothic city hall. The coin’s striking green colour is achieved by heat treating and oxidising the niobium core and applying an extra finish prior to its striking. This process has provided engraver Herbert Wähner with a brighter, almost glowing background for his exquisitely engraved designs. The reverse depicts the sun, the ultimate source of light, a portrait of Carl Auer von Welsbach and, in the Sterling silver outer ring, the evolution of lighting technology.
With a maximum mintage of 65,000 pieces in Special Uncirculated quality only, the coin contains 9 grammes of 900 Fine silver in its outer ring and 6.5 grammes of 998 pure niobium. Each coin is encapsulated, boxed and comes complete with a numbered certificate guaranteeing its authenticity.

2007-AUSTRIAN-AVIATION

By 1912 only France held more world flying records than Austria. The beautiful turquoise blue 2007 edition of our unique 25 euro Silver Niobium series pays tribute to Austria’s magnificent men and their flying machines, as well as to Austria’s contribution to aeronautics.

In 1907, Franz Xaver Wels flew several hundred metres with the kidney-shaped Zanonia glider. Igo Etrich developed the glider into a recognisable aeroplane called the Taube (the Dove) because of its bird-like wings and tail. With this machine, in 1910 Etrich’s colleague Karl Illner was able to make the first successful motorised flight in Austria, from Wiener Neustadt to Vienna and back. Both aircraft feature in the niobium core on the reverse of the coin, as does Illner himself waving from the cockpit of the Taube just before his historic flight. The silver outer ring bears the inscription “Luftfahrt in Österreich”, Aviation in Austria. The obverse shows a familiar view into the cockpit of a modern passenger aircraft, ringed by the country identification “Republik Österreich” and the 25 euro face value.

Without doubt one of the most influential of all inventions, television has dominated people’s lives for more than half a century. The Austrian Mint’s gifted engravers wonderfully evoke the birth of the ‘box’ in this 2005 edition of the 25 euro Silver Niobium series.

Considered something of a classic of retro design in Austria today, the original 1950s Austrian TV test card, used for calibration and focusing at the beginning and end of the broadcasting day, features on the purple niobium core of the coin’s obverse. The country of origin and face value are shown in its outer silver ring. Milestones in the history of television, ranging from an analogue fifties TV set to contemporary digital satellite dishes, are depicted in the silver ring on the coin’s reverse, as is the inscription “50 years of television” in German. An old fashioned TV antenna superimposed over the European section of the globe is depicted in the niobium core.

2004-150th-ANNIVERSARY-OF-SAMMERING-RAILWAY

Considered the world’s first true mountain railway, the Semmering Railway is still in full use more than 150 years after its construction. The 2004 edition of the Austrian Mint’s unique Silver Niobium series celebrates the anniversary of this technological wonder in fitting style.

Built between 1848 and 1854 by some 20,000 workers and featuring 14 tunnels, 16 viaducts and over 100 stone bridges, over the course of its 41 kilometre length this UNESCO World Heritage Site conquers an altitude difference of 460 metres. The railway’s durability is symbolised by its contrasting past and present locomotives on the coin’s obverse. The coin’s vivid green niobium core mirrors the colour of the landscape through which the railway passes, which is shown on the coin’s reverse. Here a steam train is seen crossing a viaduct spanning a deep valley framed by the coin’s outer silver ring bearing the anniversary inscription.
