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
Straight from the Garbologist's clipboard:
  • 5 recorded sales · 1 in the last year · trades only a few times a year · limited-confidence sample.
  • Following the trash: $22 → $31 → $35 → $22 → $10 — ran up to a peak of $35, then cooled back off.
  • Median moved -20% across the window ($27 → $22).
  • 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.

🧬 Should I slab it?

SLAB IT

About a 37% 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 ~$131 before the $19 PSA fee (fee only - excludes shipping & insurance), ~$112 after, vs a raw copy around $4 (est.). Grading pencils out here, especially if you hit the $150 ten.
