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
Straight from the Garbologist's clipboard:
  • 10 recorded sales · 3 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $18 → $100 → $20 → $25 → $35 — ran up to a peak of $100, then cooled back off.
  • Median moved -26% across the window ($34 → $25).
  • 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.

BORDERLINE

Roughly a 59% 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 ~$29 before the $19 PSA fee (fee only - excludes shipping & insurance), ~$10 after - about even with a raw copy ($4 (est.)). A coin flip that only pays off on a high grade.
