Sultan Abdul Halim Mu'adzam Shah was installed as the Sultan of Kedah in 1958. His Royal Highness is celebrating the golden jubilee of the coronation in 2008. Pos Malaysia released a set of three stamps to commemorate the event on 15 July, 2008. They are 30 sen stamp depicting the Gunung Jerai and the paddy field of the foot of Gunung Jerai; 50 sen stamp portraying the old office of the State Secretary of the Kedah Government; and RM1 stamp showing the town view of Alor Setar.
The stamps were printed in the format of 22 stamps per sheetlet. This is an uncommon format as commemorative stamps have been normally printed in sheetlet of 20 stamps for the past six years. The use of different pin-hole machines on the same sheetlet of this issue had created stamps with three types of perforation: P12, P13.5 and P13.5 but P12 at bottom. The number of stamps of these different perforations is not even. For each sheetlet, two stamps will have perforation P13.5 but P12 at bottom, four stamps with perforation P13.5 and 16 stamps with perforation P12.
It is also noted that Pos Malaysia has a new logo. The Pos Malaysia logo was printed on the bottom margin of the sheetlet. The new logo indeed looks better than the old one. The old logo can be viewed at http://kajang-stamps.blogspot.com/2008/03/2008-nocturnal-animals.html. I'm not sure since when the new logo has been officially in use.
