The black stuff is most probably a silver oxide/sulfide complex. If that is the case, you won't be able to remove it with any cleaning technique, without also damaging the coin.
You may try acetone, but I am almost 100% certain that it will have zero effect.
Therefore, just include this coin in your junk silver stash. That is what I have done with my black blotchy '64 Kennedys.

Yep, damaged surfaces.
Probably caused by poor storage conditions.
Describe it as if there were no picture.

Suppose it's conceivable it's just splattered with something.  |

Or one of the conditions noted above. Sorry, I get over excited sometimes.

Seeing it's pretty much just worth bullion what about try a dip? Or would that just be a waste of money on the dipping solution?

Leave it as is. It gives the coin character. Check for doubling.

It kinda looks like over spray from a can of black spray paint.
