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.

Cooling Off
The Garbologist sniffed around the sales pile.
  • 3 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
  • Its last few sales went $75 → $10 → $16 — a steady drift lower.
  • Median moved -82% across the window ($75 → $13).
  • Heads up: the last recorded sale ($16 on 2025-09-13) landed 45% 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.
