Hi all, I picked up a few quarters. Seem decent and not expensive. When I hold the coins at extreme angles, I can see a light haze in a few spots. Seems to be mostly at the high points. I'm wondering what they are and whether or not I need to worry about it. I decided to dip them in acetone and then rinse with fresh acetone. These photos are from after the acetone dip. Light spots, or haze spots, are still there. Any thoughts? The last one in the group is the most egregious, and it has not had any acetone treatment yet. The others, again, have had acetone, but also weren't this hazy to begin with, not even close. Thank you!        Edited by Numisto

@dj, can you please confirm that you used pure acetone for the bath, as opposed to something like nail polish remover?

Yes. Pure hardware store acetone. And, the haze was there before the dip.

Spotty toning or haze is usually from three sources. Either the coin was dipped and the acid ate through the surface more slowly in the toned areas.
Or a dipped silver coin is not flushed properly afterwards and the spots are caused by remaining dip.
But I think the third option is most likely for these coins. If coins in 2x2's are stored in a moist environment, the mildew that develops often causes very tiny spots forming that haze.

Hi all,
So they've all been dipped in fresh acetone and then rinsed in more fresh acetone. Nothing happened with the haze. Still there. Does that give any more insight as to what is there? And, is the grading lowered or ruined?

It's hard to tell if Acetone was used but they all might have been dipped at some point.

I mean that I dipped them in acetone and rinsed in acetone and it didn't make any difference with the haze on there. Does that help know what the problem is. Or, is there no problem?

From what I'm seeing the '56 looks like scuffs caused by that early mylar used in mint set packaging. Those are notoriously hazardous for long term storage. As far as dipped? The 1941 perhaps.

This comes up a lot. Even on a TV coin show a guy named Rick was showing many coins right form the US Mint with those spots or similar ones and some with haze. It was not explained what they are from for sure and I've read many stories here and other places about them and yet, just no one seams to know for sure. Lots of maybe this or maybe that but nothing provable.

I don't want to hijack the thread but I have 4 or so 1960s mint sets in the original packing. Should I repackage?! /WORRY! First I had heard of this...
