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.

🗑️ The Garbologist says…

Cooling Off
The Garbologist has been digging through this one's trash.
  • 53 recorded sales · 16 in the last year · trades every few months · high-confidence sample.
  • Its last few sales went $90 → $36 → $30 → $30 → $46 — ran up to a peak of $90, then cooled back off.
  • Median moved -21% across the window ($33 → $34).
  • Census check: PSA has graded 215 of this card, and only 44.2% come back a 10 — gems fairly readily.
  • Net-net, the heat is coming off — recent sales are softening. Could be a breather, could be a top; the trash doesn't say which.

🧬 Should I slab it?

BORDERLINE

Roughly a 44% 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 ~$28 before the $19 PSA fee (fee only - excludes shipping & insurance), ~$9 after - about even with a raw copy ($5 (est.)). A coin flip that only pays off on a high grade.
