Now the next question I wanted to ask is why did Malaysia uses two printers to print the same note on the same series. Any particular reason. Why didn't they use the same plate to print the notes ? Upon further examination, I realised that they even have different watermarks. The TDLR one has a small and slimmer Agung face. The BA Banknote one look very much like the Agung Portrait appearing on the banknote. Here is a list of prefixes taken from K.N. Boon catalog. As I am not familiar with Malaysian notes, I will need to seek Malaysian collectors' opinions. As what Saor Alba, it may even be a counterfeit. I am not ruling that out.
