So just got my first ever slabs. However this one appears to have some sort of marks/dirt/smears inside the slab. I checked the other slab and it has none.
What are these marks? They kind of look like dirt smeared on the inner case. I know this has been re-holdered at some point, is this likely from it not being handled properly and possibly damaged?
How does this affect value? Will it significantly lower it?
This was likely unintentional. Probably some substance on the inside of the plastic parts right from CGC's distributor. Didn't get noticed during sealing, technician probably looking closely at the edges to see if everything lined up right, got sealed correctly. Or they were eating a Snickers.
It's not a perfect world. If it bothers you, maybe you can give CS a shout out, see what their impression is.
I have had cases with similar marks. When selling them on eBay, I photograph any
