Anybody familiar with this? I have been watching some YouTube videos by Rarity7 coins, including ones where Noah unboxes CAC submissions and reviews the anointed coins and the rejects (usually wearing a sticker from John Albanese explaining why no bean). In one video, a number of MS Walkers in OGH's had been sent for approval, and a surprising number came back with a dreaded red sticker marked "pvc." Noah commented on a sort of haze on the coins from the pvc. I am familiar with the green stuff on coins from PVC flips, but have no experience with the haze. With that on my mind I was looking at some coins in a raw box and spotted this Peace dollar with a sort of foggy look: especially notable in the fields on the left; tilting the coin around there was definitely a hazy look. I could not see the classic pvc green color though. I went ahead with an acetone soak for a few minutes. after rinse and dry this is how it looked: Sorry, I accidentally repeated the pre-soak photos. Anyway the haze was gone, and the coin much brighter, I had to reduce the exposure in the second set of photos. Has anyone else observed this kind of haze? Can it be caused by something besides PVC?
