Interesting thread on the Kellogg's. I currently have two, a '70 Rod Carew and a '74 Reggie Jackson - both in PSA 8 slabs with no cracking that I can see. The slabs are the older ones with the grade and number on the same line; if not at least 20 years old I would guess they are getting close. Both cards looked to have been bagged in the slab as you sometimes see PSA do with odd sizes.
I wonder if it has something to do with how the cards were stored over time? Like if the cards were immediately pressed flat back in the day and kept that way, do those crack? Or were some of the ones that are doing this now allowed to curl up over time, and only then put into slabs much much later? I would be intrigued to know if that were the case.
