The same designs as before, but on the new Coat of Arms watermarked paper. Make sure you check the ½d & 5s of a used set as these are difficult stamps and far more common on the Springbok watermarked paper.
The Coat of Arms watermark can be found either clearly visible when held to the light, but also very indistinct, often to the point where you might not even be sure that a watermark even exists!
The same comments regarding varieties, cylinder blocks and arrow blocks that I wrote about the 1954 watermark Springboks’ Head issue, also apply to this issue.
