SGC case mystery smudging

[conor912]

So I just cracked this one. It's funny, from the outside it looked like the smudge was on the inside, but from the inside it appears to be on the outside. Its definitely not condensation as none of it is coming off despite all my efforts. The streakiness almost appears to micro-scratching of some sort, but that I still have no idea what the round blotches could be from....

I've seen this discussed somewhere before, but I can't remember where (maybe it was the SGC boards). The problem is in the plastic - it's not on the surface of the slab - either the inside or the outside.

I agree. Definitely not condensation. I personally started noticing it about 6 months ago. How about you guys?

Yikes. That's not an insignificant problem.

Yep, I have the same issue on one of my SGC graded cards. I thought it was condensation at first as well, but at least now I know where the real problem lies.
