Wow, this is an excellent thread. Although enlightening, it is also a frustrating and discouraging commentary on the current state of third party grading.
I still consider myself a newbie on this forum. After posting photos of my childhood card collection (1960s Topps) last year, some of you Net54baseball veterans strongly suggested that I submit my star cards to PSA for grading. I was going to - but life got busy - and so I put it off. Maybe it was for the best. I think I can enjoy my cards just fine without them being encased in hard plastic.
