A replacement banknote, commonly referred to as a star note, 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 banknote is simply reprinted with a symbol in the serial number,
identifying it as a replacement for an error note. Replacement banknotes
have different symbols to mark the error around the world, although the
most popular examples are "star notes".
Initially Pakistan uses “*” or “**” in the serial prefix to denote the replacement banknote. As "X" was used in general series “XX” was used to denote the replacement banknote, and finally “X” or “x” in denominator is used to mark replacement banknotes.
