Kelloggs cards?

The key to collecting Kellogg's 3-D is to keep them in a consistent environment, such as a dark 300 year old wine cellar, when viewing your collection never stare directly at the card always a sideways glance, always approach from a respectful distance, genuflecting is encouraged. If the card collecting gods choose to smile on you your card will be fine, otherwise you will see it age faster than a picture of Dorian Grey...

The idea of cracking bugs me, but it hasn't happened to me yet. I have two graded Kellogg's, a 1970 Carew and a '74 Reggie Jackson, both PSA 8's. Not sure what specifically leads it to happen, but I know they can crack in the slab. They seem fine so far. They usually live in a box in the AC, 75 degrees or so on average in NC. Nothing seems extreme, but who knows.

I love this set. It hasn't cracked at all since I bought it.

I think the cracking has less to do with where graded cards are stored now than it does how they were stored before they were graded. The Kellogg cards had a tendency to curl badly if they were not stored flat. So if they were curled for decades and then suddenly put into PSA slabs, those are the ones more apt to crack.

At least this is my working theory. I don't have enough of a collection to really try to prove it. I will say I am working on the '73 Kellogg's set, which is the one that doesn't have this problem.

High humidity causes the plastic covering to shrink in size but does not affect the cardboard part of the card under the plastic coating, this is what causes the cards to curl up if they�re not slabbed or in a rigid holder, and to crack if they are slabbed or in a rigid holder.

My story about the 1975 set. That year an employee of Kellogs gave me a 30 gallon drum of the cards in their original paper wrapping. Like a dummy I opened every one of them.

The long and short of it is that while I somehow salvaged quite a few and still have most of the set a large box of perhaps 2000 (a guess) completely curled and cracked. A year ago we decided there was no use keeping them and my son took them to his work dumpster.

One side note is that I put away many of the star cards in a small box and they have remained crack and curl free.

I have all of the other Kellogg sets put away and have not looked at them in years but believe they are still in great condition. Will find out some day I guess.

Makes sense. So for those that are already slabbed and not cracked, just keep them out of humidity?

A couple of 1970's hand cut proofs. McCarver has print lines of some sort on the back.

Also, a repack from the early 1970's of surplus stock.

I agree that the problem is caused by humidity, but it's probably a combination of paper and plastic. I went down a rabbit hole when looking this up on the web. Paper will change when it gets wet. Paper is usually rolled and dried under the pressure of rollers. The dried paper is essentially stretched leaving residual strain in the paper. When the paper gets exposed to higher humidity this allows the paper in the card to become "wet" and then when the paper redries without the stretching force being present the paper shrinks.
On the other hand, plastics are hydroscopic. They take up high amounts of water already in normal climate conditions (50% humidity in air). Direct contact with water results in even more water uptake. Hydrolysis resistance is low and as a result cracks are formed over time when exposed to water.
So it seems the paper causes the card to curl up and then the humidity causes the plastic to crack.

My only Kelloggs card, which is uncracked and still in its original wrapper.
More than likely just been kept in a shoebox its entire life?
No idea how I acquired it other than the obvious sometime in my childhood/youth.
