Awful. I have a friend with a PCGS MS67 and it started getting some purple toning. Looks awful now compared to its previous mirror like cameo surfaces.

Looks like it was the victim of improper storage.

Quote: Looks like it was the victim of improper storage. Is there any way of determining the age of the slab? I'm guessing that the coin was slabbed long before the enviro damage was present. I have a couple of tubes of steel, and over the years I've discovered a few that have developed similar problems. When I find them, I cull them from the tube and add them to my tubes of circulated steel.

Maybe it was all there when PCGS originally got it.

Quote: Is there any way of determining the age of the slab? Its not the one theyve been using for months (maybe a year cant remember exactly) now so its had some time turn if it wasnt being stored well. Thats also assuming it was never reholdered and thats it origional slab, could be much longer if that was the case.

Most relevant part of the article to this thread...
In dry air, a protective layer of oxide soon forms on an untreated zinc surface, and subsequent attack is slow. In moist air, zinc hydroxide forms first on the surface, and is then converted to zinc carbonate. If the surface has not been chromated, the carbonate takes the form of a bulky, loose layer, often described as white rust, or wet storage stain.8 In confined spaces, zinc is attacked by organic acid vapors emitted by woods, plastics, and various insulating materials 8.

MS-67 can't have rust on it. PCGS would give it like MS-60 details or something.

It probably was MS-67 before the guy ate off of it or something...

The slab is at least several years old, I could figure it out more precisely but macht's nichts.Best Regards,  George
