Thoughts on grading

[ptowncoug3012]

As most of you know, I am new to this forum. I have seen much talk about cracking a slabbed card and resubmitting to another company. Has anyone heard of a slabbed card being cracked and re-submitted to the same company? I would think you might have a shot of getting one additional grade bump.

I wonder if there is a way to prevent this. Would it offend all notions of card collecting if a grading company put an invisible stamp (one that could only be seen under flourscent light) on the back of the card with an identification number? The card would then go into the registry and therefore when we look at the POP reports, everyone knows that card no. 0000001 of T206 Cobb has been graded by SGC a 6, etc. and that it hasn't been cracked and re-slabbed as a PSA 8. Or does placing any type of ink on the back of the card simply too much to expect a collector to be okay with?

Thoughts are appreciated.
