Each 2012 Austrian Philharmonic Silver coin is struck in one troy ounce of .999-fine pure Silver. On the obverse is the inscription "1 Unze Feinsilber," or "1 ounce pure Silver," located below the Great Pipe Organ of Vienna's Golden Concert Hall, home of the Vienna Philharmonic Orchestra. The reverse of the coin displays the incredibly popular design of the Philharmonics bouquet of instruments.
On February 1, 2008, a 1 oz Silver version of the coin was issued. The Silver Philharmonics feature the same designs found on the Gold Philharmonics and are made of .999 fine Silver. The Austrian Mint decided to further expand their Philharmonic line with a 1 oz Platinum coin in 2016. The Platinum Philharmonic kept the same design as the Gold and Silver Philharmonics and is made from .9995 fine Platinum.
For the 15th anniversary of the Vienna Philharmonic Gold bullion coin in 2004, the Austrian Mint created a 1,000 oz version with a face value of €100,000. The "Big Phil" coin contains 31.103 kg of .9999 fine Gold. For the 20th anniversary, the Austrian Mint created a 20 oz .9999 fine Gold Philharmonic coin. On the 25th anniversary, the Austrian Mint introduced a new size in the series with the 1/25 oz .9999 fine Gold Philharmonic coin that is a permanent size for the series.
