This year’s highly anticipated bimetallic niobium and silver coin from the Austrian Mint features “Cosmology”. It fittingly illuminates the new year with two colours: blue and gold. Cosmology connects all the parts of the universe as a whole, and follows the evolution of it from beginning to end. The blue and gold colours of the Cosmology coin are not the result of colours applied to the coin but rather the refraction of light on an extremely thin, transparent oxide layer.
The reverse of the coin features the “European Extremely Large Telescope” or E-ELT that is scheduled for completion in 2022. This will be the largest telescope ever, anywhere in the world, and will feature a 39 metre, or almost 130 foot mirror at its base. It will be four times larger than any telescope currently in use. The details of the telescope on the coin overlap from the outer silver ring into the blue niobium core. Some of the planets known to us such as Jupiter are detailed in the design. The European side of earth is also detailed on the coin.
The obverse illustrates the all-encompassing field of cosmology, i.e. the whole galaxy: planets, stars, satellites, deep space and everything therein. This side of the coin also bears the country of issue “Republik Oesterreich” Republic of Austria, the face value of 25 euros and the year of issue 2015.
Both sides of this coin were designed and engraved by Mint engraver Helmut Andexlinger.
This new two-coloured coin is minted to a maximum of 65,000 pieces in Special Uncirculated quality only. The coin contains 9 grams of 900 Fine Silver in its outer ring and 6.5 grams of 998 pure niobium, and has a total diameter of 34 mm. Each piece is encapsulated, boxed and comes complete with a numbered certificate guaranteeing its authenticity.
