Silver and Niobium

Through the combination of silver and niobium Münze Österreich AG has achieved an internationally recognised innovation of a quality that no other coin manufacturer has so far managed to equal. The niobium tones arise without the application of colour, purely through light refraction on an extremely thin, transparent oxide layer. The combination of the coins’ two-tone niobium core with the circular design of the silver outer ring provides the ideal environment in which to explore fittingly fascinating themes.

A global innovation when launched, our 25 Euro Silver Niobium coins still combine state-of-the-art numismatic design, technology and aesthetic beauty like few others.

Every year since 2003 the coins' silver outer ring and coloured niobium core, which is attained by oxidation as opposed to the application of artificial colour, have provided the perfect backdrop for exploring suitably technological themes, from astronomy to aviation, robotics to renewable energy and electric light to television.

As well as being ideal gifts, our silver niobium coins are also extremely popular with collectors and investors.

No coin issue is like the other – from the design to the play of colors. Popular as gifts, the coins have won numerous international awards.
