Going to NGC for Appearance Review

This coin is going to NGC this week for an appearance review. From the images on the NGC site this coin did not have the discoloration when it went into the slab and has discolored inside the slab. This kind of stuff happens even with slabbed coins.

I've seen this happen before with the SAE's. I think it may have something to do with the rinse used when preparing the planchets. I'm guessing they might want to send it to NCS for conservation, at their expense of course, before making a final determination. Good luck!

I've often wondered if this would happen if the coin was not encapsulated by the TPGs. I have several 2007W ASEs ungraded in original mint packaging which are fresh, bright, and new as when I first received them.

 

Of course, it is conceivable that the planchets were rinsed improperly, but since they have remained in the capsules, perhaps they have never been exposed to the air for any length of time. Could this prolonged exposure to the air cause a reaction with the rinse? The only way to find out is to take them out of their capsules for a week or two and wait to see if anything happens.

good luck,not sure what your expecting back,other than a clean 70 coin,reholdered.

 

Good luck at NGC with the review. This is why I store my raw SAEs in Intercept Shield holders/boxes to try to delay the inevitable toning. TC

 

no but unattractive toning does. Eye appeal is one of the main keys to grades above MS-67.

 

No but who gets to define unattractive toning? The tpg. And I am not sure this would qualify. At least in my opinion.

 

Typically, that type of toning is considered neutral with regards to eye appeal. I don't find it distracting at all.

 

it didnt bother me till i noticed it. but now i cant look past it

 

So is toning bad when it comes to over all grade??

 

Good luck. I hope the appearance review meets your expectations.

Please keep us posted!

 

I could try to open the capsule on one of them to see what happens. I wonder also since both NGC and PCGS are coastal outfits in high pollution areas if this plays a role. Seems like the coins are processed and sealed in ambience which is not to the mints storage spec of "cool dry air."

 

NGC? Coastal - Yes! Pollution - No! NGC built a brand new facility a few years back, and it is supposed to be state of the art. Since high humidity is common in South Florida, I seriously doubt that they would skimp on the climate control and put millions of dollars in coins at risk just to save a few bucks on the monthly utility bill.

This whole thing is more of an experiment then anything. I want to go through the process and report the outcome whatever it is. I have a coin that I believe has changed while in their holder and I want to see what they do with it.

 

Just curious - Can you define the tpg's definition of "pretty toning"? I do not their definitions match mine. I consider a lot of the dark black/brown toning ugly.

 

PCGS talks about the different types of toning and their effect on grade (positive, neutral, negative) in their book THE OFFICIAL GUIDE TO COIN GRADING AND COUNTERFEIT DETECTION (Chapter 5, pg 58-62).

As you can see, the discussion is 4 pages long because it is not an easy subject to dissect. There are many types of toning and each type can show varying degrees that will affect whether the toning is considered positive or negative. However, the coin in this thread would always be considered to have light even toning. Here is an excerpt from the book about Light Even toning.

"This type of toning is only a few microns deep, and sometimes it is difficult to see unless it is viewed under good lighting conditions. Sometimes this toning is so light that, as noted earlier, it is ignored. If a coin has good luster that blooms through a light color, this has virtually no effect on the grade"

Defining pretty is much more difficult and much more subjective. But I guaranty that the TPG's think dark mottled toning that inhibits luster is just as ugly as you do and they do in fact penalize the grade of a coin for such toning most times. This is a quote from PCGS about Dark Even toned coins:

"Some coins have such deep toning that PCGS will not grade them, and they are returned, unsealed, as environmentally damaged."
