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:
  • 14 recorded sales · 7 in the last year · trades only a few times a year · moderate-confidence sample.
  • The recent trail reads $19 → $8 → $19 → $8 → $34 — a steady drift lower.
  • Median moved -47% across the window ($37 → $19).
  • Heads up: the last recorded sale ($34 on 2026-03-21) landed 71% above 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.
