Usually the distance between edge of the right lion head to label edge is 6mm (both top and right).
But sometimes the distance will be variable to 7mm, or less than 5.5mm, that we can see belows.
More than 1.5mm the distance difference between two labels of top of lion head to upper edge of label.
The right distance difference is 1.7mm.
Because the lion heads moved upper a little, and imprint 'Singpore' lower a little, that got them overlap.
Another interesting is the cancel is blue, not black. It is from BRAS BASAH (百胜楼).
Singapore issued ATM, red lion head.
Macau returned to China since Dec. 1999 from Portugal, so it is 10th Annv. this year. Also it is China Founded Annv. 60th, that there is special PhilaExpo in Macau 28th - 30th Nov. 2009.
