Original prints were on thin and shiny paper with sticky gum (it leaves noticeable fingerprint marks upon touching).

50¢ and $1 reprints in 1999 show similar plate number as the earliest print: 1A. However, the following year printing shows the year along with plate number.

Earliest recorded plate number for 50¢ is 2005/01. Before this 2005/1 50¢ reprint (variety), there is at least one more reprint (variety) - the paper is rough at the back of the stamp and the gum is not as the original print of sticky gum.

For $1, it is believe that there is at least one reprint - similar to the rough paper/gum as that of the 50¢ green reprint.

It is also suggested that 10¢ and 20¢ have also the rough paper/gum reprint.

Only 5¢ is known without any reprint.
