The grading math — if a raw copy grades to PSA 10

A raw near-mint copy runs about $55 (Scrydex marketplace aggregate — not a Gembook-verified comp). PSA 10 fair value here is $2,496. After the Express grading fee ($149, 20–30 business days), the spread is $2,293 — if it comes back a 10.

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.
