How about curling? How does it impact grading? Can we come up with a curling scale?
How about these possible scales for grading curling? I've heard that PSA doesn't bump the grade for some level of card curling.
1. Measure the number of 1981 Kellogg's cards that can be stacked under the bottom of the card that is curling. Keep adding cards until they touch the highest point in the curl. I will try to add pictures of this soon.
2. Measure the number of inches, in 1/8-inch increments, from the ground to the bottom of the curled card.
Can we also come up with a scale of cracking? Does anyone have ideas?
