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.
  • 5 recorded sales · 1 in the last year · trades only a few times a year · limited-confidence sample.
  • Following the trash: $12 → $8 → $8 → $8 → $8 — a steady drift lower.
  • Median moved -22% across the window ($10 → $8).
  • Heads up: the last recorded sale ($8 on 2025-12-30) landed 33% below our current value — weigh it as a single data point.
  • 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 22% 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 ~$12 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-68 after - near or below a raw copy ($2 from 7 raw sales). Not worth grading unless you are confident it is a 10.
