RIC 55b, scarce (S) / RSC 8

HER ETRVSCILLA AVG
FECVNDITAS AVG

21mm
3.54 g

Is everything ok with this coin? It has a weird surface..and what about that "rust" or corrosion?

I would think the "rust" spots are the remains of a copper coin that was found clumped together with the silver one ?

The soft detail reminds me of casting. The pinholes are supporting evidence, but both could be caused by cleaning. Are the "rust" spots on top of the coin, or "inside" the metal?

On top..like a thick stain. It isn't fourree as I thought in the first place.
I cut it's edge a bit and it is silver inside.

Looks OK to me. I have seen similar spots on some of the coins I have been cleaning. On a particular coin, I dug through the spots under the microscope to find that they extended slightly below the surface, but that coin was billon an also had green spots (BD).

What should I do? Do nothing or try to remove it? With a needle or use some chemicals?

A difficult decision, Minimax. I would have no qualms removing it if it was a common and cheap coin, but in this case, I just don't know what I would do in your place.
