Perforation Variety on Energy Saving Building Stamps

Pos Malaysia released a set of stamps (30s, 50s and RM1) on topic of Energy Saving Buildings on 9 September 2009. These stamps come with two types of perforation size - P13.25 X 13.75 and P14 x 14. The quantity of each perforation size should be the same because both perforation types can be found on a single stamp sheet in equal number. 


perforation size: P13.25 X 13.75
horizontal edge has 19 pin holes and vertical edge has 33 pin holes
type A stamp

perforation size: P14 x 14
horizontal edge has 20 pin holes and vertical edge has 34 pin holes
type B stamp

The stamps were printed in the format of 20-stamp sheet (four rows with 5 stamps in each row). The top two stamp rows have type A stamps (P13.25 X 13.75) and the bottom two stamp rows have type B stamps (P14 X 14). Therefore, the two perforation types are in equal number. This type of perforation arrangement is applied on all the 30s, 50s and RM1 stamps.

Nevertheless, I acquired a 30s stamp sheet with only type A stamps (P13.25 X 13.75). I am not sure if this type of perforation arrangement also applies on the 50s and RM1 stamp sheets. I am happy to know if you come across this type of perforation arrangement for 50s and RM1stamp sheet.
