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
Straight from the Garbologist's clipboard:
  • 4 recorded sales · 1 in the last year · trades only a few times a year · limited-confidence sample.
  • Its last few sales went $46 → $89 → $16 → $41 — ran up to a peak of $89, then cooled back off.
  • Median moved -58% across the window ($68 → $28).
  • 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.
