Interesting question (at least to me)....

[btkpath]

First some background....

So, I recently purchased a PSA 10 Kellogg's 1971 3D card (I know this isn't pre-war, but please hear me out). These cards have a thick plastic coating that imparts a 3D appearance to the card and are very prone to cracking. It arrived with several large cracks in the thick plastic coating. Clearly PSA would not have graded it a PSA 10 with those cracks, so they must have happened after the grading process and I actually thought it may have occurred during the shipping of the card to me, due to either modest jarring of the package or perhaps to temperature fluctuations (as it turns out, not the case).

So I have several questions:

1. Has anyone experienced other examples of cards significantly "changing" (meaning a change of at least several PSA grade levels) within the plastic grading cassette?

2. What are examples of cards that are prone to this change? Other than the example I gave, could this happen with coupon cards, where the coupon just detaches after grading and significantly reduces the value or grade of the card? I know that some have commented on some SGC holders trapping the card underneath the black insert, potentially tearing some fragile cards.

3. It is conceivable (in fact, this is what I originally thought was the case with the card I purchased) that a card could be packaged for shipping in original condition and arrive in significantly changed condition, with the shipping company not really being at fault either (typical handling by the shipping company and temperature fluctuations without overt evidence of a damaged package arriving). Who would be responsible in this instance (regardless of whether the card was insured)?

I would love to hear valued comments or experiences.
