Ahoy gents. I've been going through boxes of my stuff in the basement and came across my old Pokemon cards from back when I used to collect them. Seeing as I don't collect them anymore, I'm planning on tossing them up on eBay, but there's one that I wish to put up separately, which is pic related. The problem however is that the kid I bought it off of way back then (for $20) had pulled the corner of the card apart to check to make sure it was legit, I guess.

Would I be able to repair it by coating a needle in a bit of superglue, and then applying a light amount to the split corner of the card to seal it? Or should I just leave it the way it is and try to sell it as is?
