Lens coating sigma


i've acquired a sigma mini wide some time ago, and it has a kind of teardrop onto the front glass of the lens.
I've tried to clean the glass, but it's like it's something in the glass/on the coating.
It doesn't affect the pictures taken, but i'm curious of what this could be.

picure attached.



dont know how to get the picture bigger, any suggestions?

Here is the link to a bigger picture.
