Edited to add "This is an SGC holder - card image removed as it can be found on ebay"
I posted this over at PSA but I am not getting the instant gratification I desire

I was reading the post on cracking holders and thought this has some parallels.
I got this card yesterday and first thing I noticed was it seemed a bit small which prompted me to look closer. On the top and bottom, near the corners, there is some discoloration between the top and bottom panels. I don't see any obvious signs of tampering but I compared to some other SGC holders and none of them showed this kind of anomaly. I've cracked a few holders and would expect a whole side to be cloudy but after thinking about it it seems I have had some that pulled apart pretty easily once the seal was broke. I am probably just being paranoid but...
Thanks in advance for the help.
