Yesterday I spent some time at my favorite coin shop.  Digging through the "junk" bin on the table in the middle, I found a coin folder with an Australian 10$ note.  It was the commemorative folder for the 1988 $10 polymer with serial number beginning AA.  They wanted ten dollars for it!  I figured it was a great deal, considering the last I looked the notes with the AA serial numbers in the folder were going for about five times face value.
