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.

  • Its last few sales went $200 → $102 → $149 → $182 → $345 — a clear march higher.
  • Median moved +20% across the window ($151 → $182).
  • Census check: PSA has graded 217 of this card, and only 1.4% come back a 10 — a genuine condition rarity.
  • 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 1% 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 ~$466 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$386 after, vs a raw copy around $108 from 5 raw sales. Grading pencils out here, especially if you hit the $568 ten.
