The Austrian Mint’s Silver Niobium coins were first introduced in 2003, and have become extremely popular among collectors, investors and gift givers. The Robotik 25 Euro Silver Niobium coin, 9th in the series, is an eye-catching example of the detailed craftsmanship and creativity of the Austrian Mint.
The unique appearance of niobium coins is due to a process known as ‘anodized oxidation’ in which as thin oxide layer is produced on the surface. Light refraction enables different colors to arise – so there’s no need to apply color to it. The beauty of this technique shows clearly in the deep reddish-pink color of the Robotik, which is a nod to the color of Mars, featured on the reverse side of the coin.
Wonderfully detailed illustrations on the obverse feature mechanical cogs, binary coding, and a robotic version of Leonardo da Vinci’s Vetruvian man, symbolizing the interplay between electronics and mechanics that is fundamental to the field of robotics. The reverse shows a rugged Martian landscape with a European Space Agency robot exploring the red planet, with a starry sky and planet Earth shining down from the coin’s silver edge.
This coin is encapsulated, boxed and comes with a numbered certificate guaranteeing its authenticity. Issued with a maximum mintage of 65,000 pieces, the Robotik contains 9 grams of 900 Fine silver in its outer ring, and 6.5 grams of 998 pure niobium.
The first 6 coins in the Silver Niobium series sold out – don’t miss your chance to own this striking tribute to the field of Robotics.
