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.
  • 19 recorded sales · 6 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $180 → $120 → $136 → $199 → $92 — a steady drift lower.
  • Median moved -35% across the window ($290 → $189).
  • Heads up: the last recorded sale ($92 on 2026-07-25) landed 23% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 356 of this card, and only 36.8% 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 3% 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 ~$46 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-34 after - near or below a raw copy ($20 from 14 raw sales). Not worth grading unless you are confident it is a 10.
