im guessing you have not handled many us dollar notes.

He wanna action like he know all about currency lor.
USD changes only enlarge the presidents head and add in security features only. Back and stuff keep the same.
Malaysia one change color bright bright lar, change back picture la, change this la, change that la.
The best thing is they do things without proper planning lor. Take the RM2 note for example, first introduce, then remove.
Or the RM20 notes, last time got, then take out from circulation, now put back in. No proper planning wan meh whether the RM 20 or RM 2 notes are needed or not?
