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.

Cooling Off
The Garbologist sniffed around the sales pile.
  • 8 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $79 → $50 → $48 → $115 → $74 — ran up to a peak of $115, then cooled back off.
  • Heads up: the last recorded sale ($74 on 2026-03-04) landed 21% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 82 of this card, and only 13.4% come back a 10 — tough to gem.
  • 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 14% 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 ~$99 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$19 after - about even with a raw copy ($5 from 59 raw sales). A coin flip that only pays off on a high grade.
