Should I grade Slowking?
Ahead after fees: grading nets ≈ +$1285 vs selling raw (est.)
Expected grading return from this card’s own PSA grade mix (7% gem rate; grades under 8 valued at the PSA 8 price) and current graded market prices, minus a ~$25/card bulk-rate grading fee, compared against selling ungraded at market price. Treat this edge as a ceiling: PSA pop rates reflect copies collectors chose to submit, and a random raw copy of an expensive card usually grades worse. Standard grading service costs more; centering risk, turnaround time, and shipping aren’t included. The exact PSA 8/9/10 prices behind this are part of Riffle premium. Not financial advice.
