The 2009 1oz Gold Philharmonic bullion coin is struck by the Austrian Mint in Vienna in .9999 fine gold. The 2009 Gold Philharmonic is a notable financial-crisis-era bullion date and also marks 20 years since the first 1989 one-ounce issue. Demand for recognised gold bullion was especially strong around this period, giving the date more market context than a typical standard year.
