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.
  • 4 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
  • Following the trash: $41 → $10 → $10 → $10 — a steady drift lower.
  • Median moved -60% across the window ($25 → $10).
  • 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 49% gem 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 ~$16 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-64 after - near or below a raw copy ($1 from 3 raw sales). Not worth grading unless you are confident it is a 10.
