Platinum Twenty-fifth Ounce (1/25 oz), Coin Type from Austria - detailed information

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. In later years, more sizes and metals were added, including the one twenty-fifth of an ounce platinum coin denominated as 4 Euros. Because they are not in the standard circulating denominations (from 1 Euro Cent to €2), the coins are legal tender in Austria only and not in the whole Eurozone. Like any bullion coin though, their actual value 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. The obverse of the coin depicts the pipe organ in the Vienna Musikverein's Golden Hall. The reverse shows instruments of the Vienna Philharmonic, including Vienna horn, bassoon, harp, and four violins centred on a cello. Both designs were produced by Thomas Pesendorfer, who was the chief engraver of the Austrian Mint between 1993 and 2016.
