Best Darkrai Cards to Grade
The Darkrai cards where grading pays off most — ranked by net profit from raw to PSA 10 after real grading costs, with each card's estimated gem rate and risk-adjusted return. Top pick: Umbreon & Darkrai-GX (SM Black Star Promos) at +$6,352 best-case net.
Net (best) = PSA 10 value − raw value − grading cost (PSA fees as of 2026-06-28). Risk-adjusted weights every grade by its estimated likelihood from PSA population (cumulative and biased toward nicer copies — a guide, not a guarantee).
