Here what Central Bank of Malaysia reply:
Before we talk further, you need to understand what is replacement banknote:
- All the printers maybe have a very strict quality control, any defective notes will be taken out from distribution before it enter circulation. In the end,we have a very high quality banknotes in circulation. The replacements might be easy to find but error or freak notes will be a very rare item.
- The new banknotes has a very low quality and can easily torn or damaged. That possibilities happened if we take into consideration BNM reply that the new replacement banknote came from the premier set. I heard rumours before, some people say not all premier set sold by BNM since some of the set has defect on some of the notes. The printer cannot print the same serial number twice.
