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 · 1 in the last year · trades only a few times a year · limited-confidence sample.
  • The recent trail reads $22 → $10 → $10 — a steady drift lower.
  • Median moved -55% across the window ($22 → $10).
  • Heads up: the last recorded sale ($10 on 2025-11-12) landed 33% 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.

SAVE YOUR MONEY

Only a 42% gem 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 ~$49 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-31 after - near or below a raw copy ($5 from 5 raw sales). Not worth grading unless you are confident it is a 10.
