Averaged over those odds: ≈ $324.18 per slab, before selling fees.
Best case: the return if this card grades PSA 10, net of the $80.00 fee and a ~8-week turnaround haircut, before selling fees. 38% of copies submitted to PSA came back a 10, but submitted copies are hand-picked. Break-even is the chance of a 10 your copy needs for grading to pay on average.
