Key factors of the popularity of these Austrian gold coins:

Minted in one half, one quarter, and 1/10 ounce sizes
37 mm diameter
Face value of €100 or 2000 shillings

Though the Vienna Philharmonic coins have a face value of 2000 Schillings, they are only legal tender in Austria. Thus, the Philharmonic gold coins are accepted as bullion coins in other Eurozone countries but they are not accepted as money in those areas.

The Wiener Philharmonicas were designed by Thomas Pesendorfer. The obverse depicts the great organ in the Golden Hall in the Musikverein, the concert hall where the Vienna Philharmonic Orchestra performs. The words “Republik Österreich” form an arch over the organ design.

Also inscribed on the obverse are the face value in euros, the weight, the alloy purity, and the mint year.

The reverse of the Vienna philharmonic coin shows a set of musical instruments surrounded by the text: Wiener Philharmoniker or the Vienna Philharmonic.

Every year, the gold Austrian Philharmonicas are minted in four different denominations: the 1 oz., ½ oz., ¼ oz., and the 1/10 oz. Each Philharmoniker gold coin is struck in pure 999.9 fine and 24 karats gold.

The 1 unze or ounce gold Philharmonics are slightly bigger in diameter than the standard gold bullion coins like the American Gold Eagle and the South African Krugerrands.

In 2008, the Austrian Mint started to produce silver Austrian Philharmonic coins. The design of the new Philharmonicas is similar to the Wiener gold coins aside from its face value of 1.50 Euros.

The Austrian Philharmonic has a great gold collector and investor demand in the gold bullion coin market. The World Gold Council hailed the Austrian Philharmonic coin as the best selling gold bullion coin in the years 1992, 1995, and 1996.

These 24 carat gold 99.99% pure coins are not only gorgeous in their beauty and design, but are sought after for such benefits as their reputation for being:
 
a.) The best-selling coins in the world
b.) Struck in 99.99% fewer 24 carat gold
C.) Perfect in mint quality
d.) Exceptionally beautiful design of the Vienna Philharmonic Orchestra on one side and Vienna's Golden Hall on the other
e.) Able to offer immediate resale gold market value

The Vienna Philharmonic coins, as bullion coins, are a great way to invest in gold coins to hedge economic inflation. Each Philharmonic gold bullion coin is guaranteed by the Austrian government for its weight and purity, making it readily saleable in the gold coin market everywhere in the world.
