Here is a 1966 Bobby Orr graded Mint 9 by KSA SN 02524100 that I referenced in another thread.

Let's assume it had 5 owners over the years and each of them submitted the card to PSA for crossover grading. (assume unable to crossover grade because it was sheet cut or trimmed) Just curious if PSA starts every crossover review by looking to see if this KSA SN was previously submitted ?
Thanks
