SGC to PSA Experiences and Advice please

Again I dip into the vast wealth of knowledge everyone here has. I have a vintage football 57 Starr graded SGC 88 (8). I wanted to know about sending to PSA for a crossover. I do not want to crack it out and throw the dice. What experiences has everyone had with sending cards in for the crossover. Thanks as always.

Besides you would have to resubmit more than once in order to get the proper grade from psa.
I'll root for you to get an 8, but I would bet it comes back 7.

I have also sent in a SCG 8 and did not crack opent he case, PSA gave it a PSA 5. I think they have to grade the card down to show that the other company missed something!

In my experience with crossovers, I NEVER send a card unless it is cracked out first. I have cracked out a number of PSA cards for my SGC Registry set and have received the same or higher grades. I believe you are right - the company you are crossing over to is not unbiased in their evaluation! The have to send a message that the other company isn't as good and therefore their original assessment was bad! Just my opinion.
