REPLACEMENT BANKNOTE

A replacement banknote is a banknote that is printed to replace a faulty one and is used as a control mechanism for governments or monetary authorities to know the exact number of banknotes being printed. Also, since no two serial numbers can be the same, the bill is simply reprinted with a symbol in the serial number, identifying it as a replacement for an error note. The more zero,0 at the front of the prefix, the more valuable the note will be.
