I sent 6 cards in October to Laine Pearce who is doing it, Facebook group is PSA Grading Submissions Australia or similar. For these 2 they were valued at above $100USD so they cost $32 each including postage basic to me. I think the others which are lower end will be $16 each unless PSA decide the grading increases their value a lot. I’ve sent Kawhi and AD Prizm RCs so they may be valued a lot higher if they get 10s.
Grading prices are going up, the turnaround times are pushing out due to them being flooded (BGS is the same) and PSA themselves have suspended service at the moment as California State Govt is closing non essential services. So I was lucky I got these back now.
