How does this slip through the cracks?

I've had two coins not graded for the appearance of verdigris (or PVC) on the coin and without any exaggeration whatsoever, the verdigris on the coin has only been in one spot and extremely small, so how does this coin pass?
This is the part of the grading business that makes it very frustrating on us collectors.
As in this case, it's not a judgment call, but in my opinion, is a black and white issue and a definite oversight on the grader's part .

Interesting. I see at least 5 questionable spots.

Guess the unanswered question is: Were those spots there when it was graded?
Granted, it's a pretty new holder, and it's hard to imagine they appeared after slabbing....but who knows.
They must of graded that at the end of the day friday before a holiday week!

Here's the truview
Make that 13 questionable spots!

Obviously those are just emeralds in her crown.
The TrueView kills my theory....
Looks like PVC to me.
I had a coin that was in an OGH. It had a small bit of verdigris on it.
I asked about it as well. I was told that "since it wasn't active, it was ok at that grade on the coin".
Not saying good or bad about it, but just giving what was mentioned when I questioned mine.
I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment
What's the test for "being active"?
Looks like a Martian sneezed on it.

I can see 46 green spots in the TrueView!
Usually they check for molecular proton activity under the electron microscope. But once in a while you can faintly hear the verdigris calling out "Feed me!" and they know right away.
There are no martians in Canada.
We are told to believe THREE graders missed that verdigris. The slabber and a photographer just read whatever's on the teleprompter.
I had one very similar, could see it on the trueview. It's back there now for conservation and I expect/hope the fee is covered as it was there in the photo. PCGS has had it for several weeks now so I'm hoping to get it back soon. With the otherwise natural look unmolested...a gamble to be sure.
I've had good results with ms70 removing pvc on silver coins.
There is no doubt some green 'stuff' in many spots on that coin.... looks like verdigris... The copper content of that coin is 7.5%.... seems quite active for that level of copper.... Cheers, RickO
Blood test would confirm it.
How does a "dark side" coin get listed in the U.S. Coin Forum section?

I don't see them as verdigris, but as "residue" That's congealed PVC as per SoCalBigMark. From my experiences I'd say It's likely that there's a little ED below each. If so, it's scattered enough that those minute areas will blend well into their backgrounds. Looks like an easy restoration candidate. An ultra-sonic and some emulsifier stronger than acetone, maybe xylene, softens up the hardened goop and loosens it. The owner will not be displeased when it comes back from the lab.
When you've seen a lot of coins like many of the long time posters here, you'll know the green spots were on the coin when slabbed. At one of the second tier services a grader would have taken the time to remove them with a rose thorn or toothpick splinter w/o calling you for permission as it would have taken less than 20 seconds to do the job correctly. If the active contamination were more noticeable, they would have called you and removed it for free.
This is a TPGS call. This service decided the spots would not hurt the grade or rate a call or details grade. As the colonel above posted, its a good bet the surface under the green has started to microscopically etch. Nevertheless, due to their location and size, no one should notice when the green corrosion product was removed. This is a coin I'll bet PCGS would fix for free just for customer relations. NGC would probably send a note that it was a candidate for conservation if they slabbed it at all. ICG would have removed it. Don't know about ANACS. I would not let anyone doing conservation there touch my coins. Sorry.

I've played with a few coins and I've found "green" is almost always an ACTIVE color.
Yikes!
