Can This Be Cleaned?

I really don't see much hope for the coin. It appears to be a lot of Zinc oxidation and verdigris. It is no use the way it is, so might as well try something. I would try soaking in acetone overnight then seeing if any of the gunk could be loosened very gently with a thorn from a citrus plant.

Then I would soak overnight in xylol and brush lightly with stencil brush - tapping the coin with it.

If you try this, I would be interested in seeing the results!

Thanks for your input and suggestions. I may as well give it a go and see what happens.

It is a 1996 so there is no way for it to be a RPM. As far as "doubled date"? If you are referring to doubled die, then yes it is possible that a doubled die lies beneath all of that. But if it is something other than dirt and muck, you will never be able to get that off. Also if it were in fact a doubled die in the date area, a coin in that condition would be worth less than a couple of bucks. I say you will not lose anything by clearing it up a bit, but use only 100% acetone.
