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.
  • 3 recorded sales · 2 in the last year · trades only a few times a year · limited-confidence sample.
  • Its last few sales went $125 → $21 → $59 — a steady drift lower.
  • Median moved -68% across the window ($125 → $40).
  • 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.

🧬 Should I slab it?

SLAB IT

About a 33% 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 ~$142 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$62 after, vs a raw copy around $32 from 1 raw sale. Grading pencils out here, especially if you hit the $323 ten.
