I had some silver Francs from 1871 or something like that. I sold one to pay my monthly rent. Apparently if it was a year younger, it would be worth three times more, because there were only few minted that year.
Also any mistakes are worth the top dollar. Same for the notes (and post stamps).
For example there's some temporary currency which existed in Europe after the world wars - like German Marks stamped as Polish.
