This series also has nine denominations as in the first except that a $20 note was introduced to replace the $25 note of the Orchid series. The dominant feature is a bird on the left side of the front of each note. The birds depicted on the notes are noted for their strength, adaptability and independence which characterize the young Republic of Singapore with the potential of soaring to greater heights in its progress.
On the front, all notes have the Singapore Arms, a watermark of a lion's head and the signature and seal of Minister for Finance and Chairman of the Board of Commissioners of Currency, Singapore. With the exception of the $1,000 and $10,000 notes which have two security threads, each note has a security thread embedded vertically across it.
