What would create toning like this?

It reminds me of the haphazard toning that occurred on some of the huge collection of Morgan's I inherited. They were all stored the same way in those old tan paper flips.

Some toned nicely and a bunch graded MS at PCGS- some didn't fare as well and toned really strangley/darkly and it killed the eye appeal. They were all from the same roll/same VAM.

I seem to recall a past discussion where 100% of the posters agreed there was NO ONE older than you!

 

The methuselah of coin collecting. Doug remembers when ancients were in daily circulation

 

As far as the coin my thought is it was in a paper envelope that either got wet or was stored in a moist environment

 

I bought the coin in 2007 from this next image. The second image is a coin I could have bought at the same time but it has FH on the holder and the price was just too much. They were already graded at the time. The images above were taken last month at FUN. In hand I believe the reverse is turning darker. I'm not sure of the age of the holder. I'll post an image of it in a few.

 

I believe that particular NGC holder , combined with storage methods, combined with air pollutants has caused this.
Ive seen this happen before, albeit mostly small coins like dimes

 

@Conder101 Could you help with when this slab was being used?

 

1992 -1995 My NGC 5.

 

I have a 1971-S proof Ike with weird toning that I believe to be from exposure to moisture. The reverse is completely unaffected, and I'm curious as to how this happened.

 

Is that thing still in the OGP ?? Certainly youve dubbed it- the snake skin Ike ?

Or the Zombuck ??

 

If this was a steel plate I’d say it looks just like Mill Scale. The scale on steel flakes off and produces sharp edges also. Scale and toning are both a surface oxidation and can be chemically removed and after that the surface will then build up again, rust on steel and tarnish on silver. The silver items were polished less that a year ago.

Gone.

 

Why did you jack my thread with this?

 

Sorry. I can see your point. I shared the coin to show that it had a similar, unnatural toning pattern like yours, but I didn't mention that at first. I'll see if I can delete them. If not, then maybe @GDJMSP can.

 

I was able to edit out the last post, but not the first.
