petecldNo, the holder doesn't look tampered with. Poorly taken images.
SGC is TOUGH on Cracker Jacks, VERY tough. I had cards that were ex/mt but stained, some more than others, and they came back "30" and "40". This does look like a decent card but I'm not surprised by the grade at all.
Considering the quality of the SGC holders I don't see anyone opening one and being able to replace the card without it being very obvious.
