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.

Trending Up
Straight from the Garbologist's clipboard:
  • 4 recorded sales · 2 in the last year · trades only a few times a year · limited-confidence sample.
  • The recent trail reads $15 → $15 → $10 → $40 — a clear march higher.
  • Median moved +67% across the window ($15 → $25).
  • Heads up: the last recorded sale ($40 on 2026-06-17) landed 21% above our current value — weigh it as a single data point.
  • Net-net, the momentum points up — real buyers are paying more, more often. Not a promise, just what the garbage is telling us.

About a 33% 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 ~$143 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$63 after, vs a raw copy around $6 from 6 raw sales. Grading pencils out here, especially if you hit the $370 ten.
