The Vienna Philharmonic (German: Wiener Philharmoniker), often shortened to just Philharmonic or called the Austrian Philharmonic, is a bullion coin of gold, silver, or platinum produced by the Austrian Mint (Münze Österreich). The coin is named for the Vienna Philharmonic orchestra, which inspired the design of both sides. It was introduced in 1989 as a one ounce and a quarter ounce gold coin with a face value of 2,000 and 500 Austrian schillings respectively. In later years, more sizes and metals were added. It is generally one of the world's best selling bullion coins.
In 2002, with the adoption of the euro currency, the nominal value of the quarter-ounce gold coin was changed to 25 Euros. Like any bullion coin though, their actual value is unrelated to the face value, and is based primarily on the metal content and the spot price of that metal on the commodities markets.
The design on the coin remains the same each year; only the year of issue changes. Both the obverse and reverse were designed by Thomas Pesendorfer, who was the chief engraver of the Austrian Mint between 1993 and 2016.
The obverse design of the coin features the pipe organ from Goldener Saal (the Golden Hall) in the Musikverein, the concert hall in Vienna where the Vienna Philharmonic orchestra plays.
