Bruce BabcockI know nothing about the PSA 8 Wagner other than the rumors that have been referred to over the years, and alluded to here.
However, I have heard of grading companies rejecting cards as "altered" which do not exhibit "minimum thickness." Allegedly, cards can be compressed under pressure, which increases the over dimensions slightly. Then the card is trimmed down to the normal size. Presumably the grading companies would detect such minute variations in thickness by using a digital caliper. A relatively inexpensive precision caliper is accurate to 1/1000 of an inch. I would have thought that such compression would "spread" the surface of the card so that the gloss on a high end card would be disturbed.
