Yeah, cuz they don't. If you take a close look at the bottom of the John Axford there, you can see the cuts as well as the impressions in the card. Does the pattern look familiar?
It's from sealing the pack. The card appears to have slipped a bit and was sitting too close to the edge of the pack as the end was heat sealed and stamp cut. And now, I have a 1/1 die cut 2012 Bowman. BOOM!!!!
