Quantum physics reveals that the world has much more to offer than meets the eye. It explores the fascinating domain of the tiniest constituents of matter – electrons, photons and atoms – which defy the laws of classical physics.

Among the most spectacular of the Austrian Mint’s products are our innovative Silver Niobium coins. The coloration here is not created by color printing, but by the targeted and highly precise refraction of light. Exploring technological themes, the unique and highly sought-after 25 euro coins are exclusively produced by the Austrian Mint using state-of-the-art technology developed in Austria. 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.

This beautiful frame allows you to display your coins in a completely new way. It makes coins appear to be floating inside its transparent silicon membranes.
With each Silver Niobium coin being completely different from the last, both in terms of its colour and subject matter, it is little wonder that they have won numerous international award and are extremely popular as gifts and with coin collectors.
So, it is hardly surprising that many of them are sold out and can only be found for sale in the secondary coin market, although often at a considerable premium. We do have the last three editions still in stock, however.
The beauty of niobium is that colours do not need to be applied to it as they are created during the oxidation process. By means of ‘anodized oxidation’, a very thin oxide layer is produced on the coin surface and subsequent light refraction enables different colours to arise.
