The Austrian Philharmonic one-ounce gold bullion coin is a highly sought-after investment coin made of 99.99% pure gold. It was first minted by the Austrian Mint in Vienna in 1989 and has since become a popular choice for investors and collectors alike.

The obverse (front) of the coin features the Great Organ of the Golden Hall in Vienna's Musikverein, home to the Vienna Philharmonic Orchestra. The reverse (back) of the coin depicts a selection of orchestral instruments, including a cello, four violins, a Viennese horn, and a bassoon. The inscriptions on the coin include the coin's weight, purity, and denomination, as well as the words "Wiener Philharmoniker" (Vienna Philharmonic) and the year of issue.

The coin is 37 mm in diameter and has a thickness of 2 mm. It has a face value of €100, although its actual value is determined by the current market price of gold. The coin is legal tender in Austria and is therefore exempt from Value Added Tax (VAT) in the European Union. It is also recognized and accepted by bullion dealers and investors worldwide.

The Austrian Philharmonic one-ounce gold bullion coin is considered one of the most beautiful and well-designed gold coins in the world. Its high gold content, stunning design, and worldwide recognition make it a popular choice for those looking to invest in gold.
