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.

Trending Up
The Garbologist has been digging through this one's trash.
  • 3 recorded sales · 1 in the last year · trades only a few times a year · limited-confidence sample.
  • Following the trash: $10 → $7 → $18 — a clear march higher.
  • Median moved +26% across the window ($10 → $13).
  • Census check: PSA has graded 231 of this card, and only 16.5% come back a 10 — gems fairly readily.
  • 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 16% 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 ~$78 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-2 after - about even with a raw copy ($5 from 22 raw sales). A coin flip that only pays off on a high grade.
