Niobium Coin Article Originally by Louis Golino and Updated April 2020 by CoinWeek …..
The Austrian Mint is one of the world’s oldest mints, with historical roots that date back to 1194. It is best known for its Philharmonic silver and gold coins, which are among the world’s most widely traded bullion coins,however since 2003 the mint has issued a 25 euro coin that feature an outer ring of silver and an inner core of of a special oxidized metal that can create multiple different colors. This is known as the Niobium Coin Series.
This has become one of mint’s most well-known and popular collector series, and it honors Austrian, European, and global contributions to science and technology. It is a widely collected and innovative series, the first numismatic series in the world to use niobium, a metal that is much rarer than silver.
Niobium was discovered in 1801, and is used primarily in the aerospace industry and jewelry manufacturing. The only other countries that make a niobium coin are Canada, Latvia and Luxembourg (though Luxembourg utilizes the Austrian Mint). There are other “Branded Collector Coins” also produced under license with Liberia, Rwanda, Sierra Leone, Mongolia and Palau.
These Niobium Coin have a striking appearance because the niobium is oxidized during the preparation of the coins, and it is done differently for each issue in order to give the Niobium Coin a different color. Because the coins are popular all over the world, especially in Europe, their mintage was raised with the 2005 issue from 50,000 to 65,000, a level which has been maintained through the current issue.
65,000 coins is not a low mintage by any means, but because the coins have an established core of collectors, they have mostly done very well on the secondary market. This is especially true of the earliest issues that are difficult to obtain even from European coin dealers, and a number of other issues in the series have increased considerably in value since they were issued.
The last few coins in this series were initially available directly from the Austrian Mint for about € 76.80 *incl. 20% VAT, and typically go for about $90-95 USD from dealers in the US when first issued.
The fact that these Niobium Coin have compelling designs and sport a different color each year also helps support strong interest in the series because it makes the coins more interesting than a series with a stagnant design. Moreover, the Niobium Coin designs have become more intricate in recent years, especially on the outer silver ring where design elements have been added.
In addition, the color of the niobium core has evolved from a single uniform color to the use of two contrasting colors incorporated into the design elements on the core. Not surprisingly, a number of Niobium Coin in the series have been nominated or won Krause Coin of the Year awards in various categories.
In 2007 the amount of niobium in the Niobium Coin was changed from 7.15 to 6.5 grams, changing the total weight when combined with 90% pure silver from 17.15 to 16.5 grams. The diameter has been the same since the 2003 issue at 34 millimeters.

A word about values: There is a dearth of accurate and updated valuation sources for modern world coins and Niobium Coin compared to what is available for American coins. Like many collectors I do not find the market values contained in Krause Publication’s Standard Catalog of World Coins 2001-Date to be very accurate. That leaves two main useful sources, which are recent e-Bay sales and values listed in the Lighthouse Euro Catalog, which more accurately reflect the levels these coins trade at when sold by European dealers.
Sources: Lighthouse Euro Catalog 2014; 2013 Standard Catalog of World Coins 2001- Date; e-Bay; Austrian Mint web site; and “Austrian Euro Coins ‘Silver-Niobium Coins 2003-2013’ Collector Coins,” by Maciej Czekaj, posted on January 23, 2013 online (link appears in text above).
