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.

  • Census check: PSA has graded 431 of this card, and only 4.2% 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.

🧬 Should I slab it?

SLAB IT

About a 4% 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 ~$133 before the $79 PSA fee (fee only - excludes shipping & insurance), ~$54 after, vs a raw copy around $5 (est.). Grading pencils out here, especially if you hit the $1,128 ten.
