Response to the glitter paint issue. This feature is used on 20,10,5 euro bills at the back. They new introduced 2003 and 2004 Hong Kong banknotes have glitter paint on the notes, Croatian banknotes have this, Older pre-euro Portugeuse banknotes had them, Pre-euro German banknotes as well, I think the new Japanese 2000 Yen note, and New Swedish banknotes share this feature. There's more but I can't remember..............
