How much is an Austrian Schilling from 1969 worth?

Zero. Sorry. In 2002 one schilling was about 10 USA cents, but Austria joined the EU common currency and now the Euro is the "coin of the relm". Schilling coins can no longer be exchanged for "cash". But a schilling coin DOES make a good keepsake! ;-)

Wrong. Schilling coins (and banknotes still in circulation at the time of the Euro changeover) can be exchanged indefinitely for cash at the Austrian Central Bank. I wouldn't bother making a special trip, though -- one schilling is worth about EUR 0.07, or roughly one U.S. dime.
