I purchased a few coins and one looks like it has a haze over it. I am trying to figure out how long ago it was slabbed and was curious if there was an indication in the PCGS or NGC coding sequence.
I don't know about the number, but you can tell by the slab type for PCGS. Look on their page for the history of the changes.
NGC not really, PCGS sort of. The slab generations themselves are much more telling. Post some pictures
The reason I ask is that if there was residue on the coin I find it hard to believe that PCGS would slab it, but that is exactly what it looks like. If I knew it was an old slab I would conclude that it was not as present at time of slabbing and must have emerged over the years. But if it was recent, and it looks like a current slab then I would have to think differently.
Perhaps it was dipped (or something), was not properly rinsed and dried. The coin was evaluated and slabbed, and then the residue formed like a mutant bacteria inside the slab over many years, waiting for the monkey Outbreak.
Only in rough numbers, but some types of slabs and labels were used for periods as short as two weeks. Others for eight years. Pics
As others proposed, it may have been improperly cleaned prior to slabbing, and the hazing formed later. Another possibility is that the hazing is the reason that the coin graded 63PL. Based on detail only, I think the coin is about a 64+ to 65.
So would anyone think that cracking this open and removing the haze would be worth the risk of the current grade?
Seems like a lot of effort to me, for something that might not be successful. That's just my opinion though. If you believe it is worth the risk then you can feel free to try.
