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.
  • 6 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $67 → $81 → $35 → $25 → $50 — ran up to a peak of $81, then cooled back off.
  • Median moved -48% across the window ($67 → $35).
  • Census check: PSA has graded 29 of this card, and only 48.3% 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.

SAVE YOUR MONEY

Only a 48% 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 $80 PSA fee (fee only - excludes shipping & insurance), ~$-51 after - near or below a raw copy ($2 from 10 raw sales). Not worth grading unless you are confident it is a 10.
