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.
  • 6 recorded sales · 0 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $37 → $17 → $19 → $6 → $14 — a steady drift lower.
  • Median moved -15% across the window ($17 → $14).
  • Heads up: the last recorded sale ($14 on 2025-04-07) landed 50% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 214 of this card, and only 8.9% 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.

🧬 Should I slab it?

SLAB IT

About a 9% 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 ~$227 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$147 after, vs a raw copy around $16 from 28 raw sales. Grading pencils out here, especially if you hit the $1,424 ten.
