By the look of the scan I would say that the spotted part of the stamp was probably produced by some sort of tape/covering and there has been some sort of chemical reaction.
The Gold of the Queens head is always the last item to be printed on the stamp and in this case the spots are on top of it. Therefore it cannot be a variety or an error.
My guess is it was soaked up against part of a security envelope and the ink transferred to the stamp.

I was almost certain that it was a chemical reaction, but the philatelist's enthusiasm for this curiosity gave me hope that I would find a new addition to my collection. I will settle for a stone from a stream rather than a rare gem.

I found this right side stamp in a lot of UK stamps I purchased recently.

Can someone tell me if it is a variety or it is a sun or chemical interaction.
Many thanks in advance
