    I've only done one and it went from a 9 to an 8.

    I have, ISA 6 to PSA 6. I pulled a Magic/Bird/Erving RC at the National, and just wanted it protected. ISA had a free grading offer, so I had them slab it until I could send it to PSA. 6 is the right grade, for the centering.

    I'm actually very surprised that they crossed over at all let alone nearly equal or very close. Very good info

    Great info. I would be curious to know if anyone has tried to go from ISA 10 to no worse than PSA 9?

    I submitted for crossover to PSA a 1991 Topps Desert Shield Craig Biggio which was graded ISA 10. It was deemed PSA 9 and I'm okay with that.

    That was my only instance of ISA>PSA
