GPK Price Guide Value iGPK Price Guide Value is a recency-weighted market value from REAL sales of this exact card+grade (recent comps count most, outliers stripped) — steadier and harder to game than a single 'last sale', which can be one lucky auction or a shill bid. When a card has few or no recent comps, we estimate transparently from its own older sales, its other grades, and comparable cards (same subject/set/rarity tier), factoring subject trend and scarcity — and we LABEL it as an estimate until real sales arrive.

  • Census check: PSA has graded 41 of this card, and only 4.9% come back a 10 — a genuine condition rarity.
  • Net-net, the momentum points up — real buyers are paying more, more often. Not a promise, just what the garbage is telling us.

BORDERLINE

Roughly a 5% gem rate on this card's own PSA pop - graded pop is self-selected (best copies get submitted), so a random raw likely grades lower. Expected ~$329 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$249 after - about even with a raw copy ($200 from 4 raw sales). A coin flip that only pays off on a high grade.
