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 popped the lid on this card.
  • 18 recorded sales · 2 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $190 → $276 → $123 → $750 → $300 — ran up to a peak of $750, then cooled back off.
  • Census check: PSA has graded 396 of this card, and only 9.3% 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.

Automated analysis generated from this card’s real recorded sales and PSA population data — no opinions, no predictions guaranteed. Entertainment and research only, not financial advice.

SAVE YOUR MONEY

Only a 0% 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 ~$55 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-25 after - near or below a raw copy ($7 from 53 raw sales). Not worth grading unless you are confident it is a 10.
