Should You Grade?
Negative expected value ($-6.91) — while a PSA 10 would be profitable, the probability-weighted outcome across all grades means you lose money on average at this grading tier. Low grading population — gem rates based on only 41 graded cards may be unreliable, and the market for this card in graded form may be illiquid. Only 73 sales per year — it may take time to find a buyer at full price. PSA 10 profit of $0.16 is thin — grading fees and selling costs eat most of the margin.
Factors in grading cost, turnaround time, and compounding — how fast you can reinvest profits into the next flip.
Shows the best-value tier from each grading company based on EV, cost, and turnaround. Pop = total graded population; 10s = grade 10 count.
