It's supposedly graded by PCGS as MS64RB. But it doesn't show up on PCGS population statistics?

I am pretty sure I am looking at the right one? Or am I going blind?
As I understand it, PCGS pop reports for world coins can be unreliable - they didn't start counting them until a few years after they started grading world coins.
Meanwhile, I'm left wondering how a coin with obvious verdigris patches made an MS grade at all.

Maybe the verdigris "Grew" after it was slabbed.
Normally a coin in this condition would come back in a Genuine UNC Environmental Damage slab or bodybagged.
Unfortunately it does happen on coppers which have been slabbed. Verdigris can occur from a number of chemicals primarily Chlorine when it reacts with oxygen and water. As such what I believe has happened is it has been subjected to chlorine contamination prior to slabbing and then stored in a water rich environment after slabbing giving no indication of Verdigris damage upon grading. However I do believe that the PCGS Guarantee extends to Verdigris developing post slabbing.
I wish they'd put the slab numbers in auctions so you could accurately authenticate wtf they are selling. I found the RD and RB numbers on the PCGS pop but there's no coins slabbed with those numbers. Strange. Also strange that it appears to be in a pronged holder which are newer.
well that verdigris is quite common on these tokens
I can say that I have seen heaps of slabbed coins (not tokens) with verdigris
copper corrodes - doesn't need a chlorine dip to set it off
I actually called them up and ask for the cert no.

The photos on PCGS suggest that the verdigris were there at the time of the slabbing.
It was listed as "ND 5 Shil KM-Tn5.1 Internment Camp, RB(Regular Strike)" rather than "(1943) 5 Shil KM-Tn5.1, BN(Regular Strike)"
nicely done kchan
could be that PCGS is giving a bit of leeway on this coin given that they commonly have this issue? they may also think that the verdigris is inert?
There are 2 PCGS coin numbers for that RB coin and no coins for the one listed in the population report.
634853, and 523510
There are a few coins that have more than one coin number by accident.

RG seems to think so. I am no expert.
Were all of these minted in 1943? Otherwise how can they tell the date?
