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.
  • 5 recorded sales · 1 in the last year · trades only a few times a year · limited-confidence sample.
  • The recent trail reads $39 → $52 → $44 → $30 → $38 — ran up to a peak of $52, then cooled back off.
  • Median moved -16% across the window ($45 → $38).
  • Census check: PSA has graded 156 of this card, and only 4.5% come back a 10 — a genuine condition rarity.
  • 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.

SLAB IT

About a 5% gem (PSA 10) 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 value ~$437 before the $299 PSA fee (fee only - excludes shipping & insurance), ~$138 after, vs a raw copy around $24 (est.). Grading pencils out here, especially if you hit the $5,750 ten.
