MikeU"Breaking his cards out for Kevin to examine would offer little insurance."
That I agree with, as soon as you break the card out, you have essentially voided the warranty. Many alterations will be relatively hard to detect in the slab. You will only be able to get the relatively obvious ones, which Joe should not have much of an argument with for refund. However, under 100X magnification in the slab, you can strongly solidify ones suspicions. The slabbed pile of "reasonable doubt" cards will be the hard part. If you truly wanted to complete the story, a agreed break out session with PSA supervision would need to take place.
