Is all the replacement note of 3rd Series printed with prefix "Z"? I would say at this moment the answer is "Yes". But, there are also rumours say that not all the RM1 note with prefix "Z" is the replacement note. Anyway, not many of the replacement note with prefix "Z" appear in the market. I have seen Prefix "ZA, ZB, ZC, ZD, ZE, ZG and ZW". Anyone has seen replacement note of RM1 with other prefix than mentioned above?
