In 1992, 1995, 1996 and 2000 the World Gold Council declared it the best-selling gold coin in the world. Since its introduction in October 1989 up to 2012, more than 14 million Philharmonics have been sold for a total weight of 9.6 million ounces or approximately 329 tons of gold. Since February 1, 2008, a 1-ounce silver version of the coin with a nominal value of €1.50 has been issued, struck from 99.9% pure silver. Unlike the reeded edge of the gold coin, the edge of the silver coin is smooth. Coins are shipped in boxes of 500, called "monster boxes." Each monster box consists of 25 tubes of 20 coins each. Sales of the silver Philharmonic have been brisk with over five million coins sold, equal to 1,800 tons of silver in the 5-year period of 2008 through 2012. The mint introduced a one ounce platinum coin with the same design as the gold and silver in 2016. Like the gold coin, it has a face value of €100. The purity is shown as 999.5 with the obverse of the coin reading "1 UNZE PLATIN 999.5." The Vienna Philharmonic is currently the only European bullion coin with a face value in euros, although it is only legal tender in Austria. In 2004, the Vienna Philharmonic accounted for 35 to 40% of sales in Europe. It is also popular in Japan and North America. Gold Philharmonic specifications: Silver Philharmonic specifications: Platinum Philharmonic specifications:  For the 15th anniversary of the Vienna Philharmonic bullion coin in 2004, the Austrian Mint created a 1,000 ounce version with nominal value €100,000. The "Big Phil" coin consists of 31.103 kg of pure gold. Dimensions were increased by tenfold over the one ounce coin yielding a diameter of 37 cm and 2 cm thickness (10 times thicker; 10 times wider; thus 1000 times heavier than the 1 ozt. coin). It was one of the largest coins with the highest denomination until it was eclipsed in 2007 by the Royal Canadian Mint's 100 kg version of the Canadian Gold Maple Leaf with a face value of CA$1,000,000. In keeping with the fifteenth anniversary theme, only fifteen €100,000 Philharmonics were produced. The coin was unveiled in front of the Wiener Riesenrad Ferris wheel in Vienna. One of the coins is displayed in the foyer of the Munich headquarters of precious metals company "pro aurum".
