Malaysia 50 cent stamps

As you   can see these are varied stamps but what makes them common is the denomination...50 sen and of course all are Malaysian.I had to compile these stamp images.There are several more stamps of the same denomination which will come in another posting
What makes these stamps special is that any of these stamps can be used on a postcard to be sent to anywhere in the world...one price anywhere to the world on a postcard...talk of equality among stamps!
For more details please ask me.
