Thanks for sharing and you are definitely brave for cracking the slabs! The PSA one was definitely most anxiety inducing one to watch. The others were more forgiving. However, I do like your approach putting it inside a bag so debris does not fly everywhere. Hope you get back some wonderful grades! Have a wonderful Friday & better weekend!
The first time is when the real nerves happen. I suggest buying the least expensive cards in slabs to practice on, first, then graduate to the cards you're really after. It takes some patience and practice to find your form. The PSA ones seem to always crack differently. The one in this video was a little bit of a booger. Thanks for watching!
