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 popped the lid on this card.
  • 4 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
  • Its last few sales went $80 → $192 → $67 → $100 — ran up to a peak of $192, then cooled back off.
  • Median moved -39% across the window ($136 → $83).
  • Heads up: the last recorded sale ($100 on 2025-05-25) landed 29% 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.

🧬 Should I slab it?

NO RAW PRICE YET

About a 42% gem (PSA 10) rate on the 1988 GPK PSA pop (all sets that year) - graded pop is self-selected (best copies get submitted), so a random raw likely grades lower. Expected value ~$79 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-1 after. No raw (ungraded) sale of this card is on record, so there is no raw price to compare grading against yet.
