A new variety of the Singapore $5 banknote is finally spotted, with one square dot on its reverse. The small brown symbol is printed beneath the word ‘Garden City’ on the bottom left corner. These symbols have been introduced on polymer and paper notes since 2007, as a new security feature used by the Monetary Authority of Singapore (MAS) to authenticate the notes.
Similar to the latest banknotes in general circulation, these polymer notes bear the signature of MAS Chairman SM Goh Chok Tong. Serial numbers for this variety are believed to start at 3AA. So far, I have sighted the following prefixes in circulation: 3AC, 3AD, 3AF, 3AH, 3AJ, 3AN. If you happen to see any other prefixes for this new variety, please leave a message in the comment box below or drop me an email.
Earlier today, a bank teller has informed me that she had seen a $1000 banknote with one triangle on its reverse, with its serial number starting with 2. If you happen to come across such a note, a scan of the note is greatly appreciated.
