Acetone does not remove authentic oxidation. Every time one of the knowledgeable members here recommends it after seeing coins in this condition only continues to spread the "acetone myth." Thankfully, an acetone soak should not hurt the coins.
True, but it don't hurt to try, seeing that you won't be doing any further damage.
Benzene won't touch silver sulfide any more than xylene or acetone. The only thing to do is reduce it chemically (or, of course, scrub it off physically, further ruining the coin).
I can't imagine anything on a coin for which benzene would be more effective than xylene. Please stick with xylene if you have to remove nonpolar organic stuff. (And I say this as someone who remembers being able to buy benzene in stores.)
But please experiment on the most common/worn/damaged examples from the group before moving on to the better ones.
