The interesting thing about these definitive stamps is that the stamps from the 20-stamp-sheet (click here to see the image) and the stamps from the 100-stamp-sheet (see below) are different! These stamps are different in two features. Firstly, the stamps from 20-stamp-sheet have "2010" behind the word Malaysia but the stamps from 100-stamp-sheet lack "2010". This feature is good enough to claim that the stamps from the 100-stamp-sheet are "new" againts the stamps from the 20-stamp-sheet. Secondly, the 50s, 70s, 90s and RM2 stamps from the 100-stamp-sheet do not have white borders on right, left and top, but the other denominations 30s, 60s, 80s and RM1 are just the same as the stamps from the 20-stamp-sheet with white borders on right, left and top. I show an example of this border variation on 70s stamp (see image below).
Nevertheless, the micro-printing is still applied on the stamps from the 100-stamp-sheet. The design of sheet margins for the 100-stamp-sheet is similar as those of the bird definitives. So, serial number and Pos Malaysia logo are applied on the top margin of the stamp sheet. Time to hunt for serial numbers..... hehehehehehe
