There's a lot of good tips/vids on Youtube about cracking out cards.
I have a few Beckett ones I'd like to crack out as I don't like not being able to see the cards clearly in those holders in those plastic bags.
My PSA cards are a different story, and although I purchased them that way, instead of paying for the grading, I think I'll leave those ones alone as I can see the actual card a lot clearer.
