There is something to be said for collecting old coins which are never expected to be perfect (though I can also appreciate the attraction to perfection)

Well, this coin is still in the acetone, still with the surface haze, waiting on the next move. In researching proof Kennedy half dollars with collar clashes, I turned up only one other legit example (a 2000-S on Reddit), so I really don't want to foul up this error coin.

I have 91% isopropyl alcohol from a pharmacy. Are there concerns that it might contain contaminants or additives? If anything will show a problem, it would be a proof coin surface. Maybe xylene is a safer bet?

From what I can find there is 91% isopropyl alcohol with the remainder ingredients being 'purified water'.

I agree. It should be fine, but you can test it. Place some in a really clean glass bowl and let it evaporate. If there is no residue on the glass, all is good.

If all else fails, I'm thinking Mark and Digger can make something that would work!

Any further results with the adhesive/haze?
