Austrian Coin Identification

I've hunted around on numista and worldcoingallery for coins and tokens of Austria dated 1976, but didn't find anything so far.

Hello, this is a sterling silver (925 = .925 = Sterling Silver) coin (or medal), struck during 1976. The striking seems to be of high quality (showing perfect proof matting and mirror-like cameo surfaces). I guess, that the spots are on the plastic, not on the coin itself.

The ones shown in the shop (mentioned by philadelphian) are made of non-precious alloy (neusilber = new silver or german silver, which is actually a good non-rusting alloy of non-precious metals = copper-nickel alloy).

It's a commemorative bullion round from 1996. They issued all sorts of medals, both official and unoffical, with famous Austrians of the past 1000 years. This looks like one of the unofficial (private) issues since it is missing a denomination and other official elements (year of emission, name of the country in official format).
I remember being in Vienna for the 1000 year celebration in 1996. They were celebrating the 1000 year anniversary of the first official mention of "Austria" in a document, it was spelled "Ostarrichi" in a grant from Otto III in 996.
