CGC grading tightness over the years question
I was a collector in the 80's before CGC, and about to get many graded. I am however curious as to CGC's grading timeline has been, were they tighter graders in the beginning, or looser graders? How are the CGC grades comparable to the first few years? I know they set the standard, so I'm sure grading styles have fluctuated with more and more information, just curious if there are more allowances for production flaws, fingerprints, etc. nowadays. Thanks,
Nate
