The grading math — if a raw copy grades to PSA 9
A raw near-mint copy runs about $45 (Scrydex marketplace aggregate — not a Gembook-verified comp). PSA 9 fair value here is $128. After the Regular grading fee ($79.99, 40–50 business days), the spread is $3 — if it comes back a 9.
Not an expected value: grading outcomes are uncertain and a lower grade changes the math entirely. Spread is before marketplace selling fees. Shown only on cards with ≥MODERATE price confidence. PSA fees verified 2026-06-11.
