The niobium coins from Austria are among the most sought-after collector coins due to their uniqueness. They have been minted annually since 2003 and are made of silver and niobium.
In contrast to bullion coins made of gold or silver, these bi-metal coins are particularly popular with coin enthusiasts. Some series are already sold out and are only available on the collectors' market, as the demand for niobium coins has been rising continuously since 2003.
Customers particularly appreciate the unusual two-tone look. The different colors of the vintages are achieved by refracting light. The technique of "anodic oxidation" is used for this. It is not only the two-tone coloration that is very special: niobium is a rare chemical element that belongs to the transition metals. It has exceptional properties and is therefore frequently used in the aerospace industry.
With the purchase of niobium coins you own a piece of Austrian history of the highest quality. The face value of the coin is 25 euros. However, the actual value increases from year to year. This is because the mintage is limited and only available in the special "hand-struck" quality. This means that the coins are individually inspected and packaged immediately after minting to ensure first-class condition.
