justin...a bit off topic but I thought you may like this site. Reserve Bank Of Australia - History Of Bank Notes. http://banknotes.rba.gov.au/historybanknotes.html There's some great links way down the bottom of the page in very fine print.

This is an American site, it is a subsidiary of PCGS I believe http://www.pmgnotes.com/grading/notes-we-grade.asp It lists Australian notes, I have seen these on Pawn Stars before, they sent away and had them come back graded. Prices - http://www.pmgnotes.com/services/services.aspx
