Card # 1b⇄ 1AOozing Ozzy
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.

🗑️ The Garbologist says…

Too Thin To Call
The Garbologist sniffed around the sales pile.
  • Only 2 recorded sales on the books — not enough for a trend without kidding ourselves. The last one changed hands at $67 on 2025-07-29.
  • With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.

Automated analysis generated from this card’s real recorded sales and PSA population data — no opinions, no predictions guaranteed. Entertainment and research only, not financial advice.

Only a 51% gem rate on the 2017 GPK PSA pop (all sets that year) - graded pop is self-selected (best copies get submitted), so a random raw likely grades lower. Expected ~$48 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$-32 after - near or below a raw copy ($4 from 4 raw sales). Not worth grading unless you are confident it is a 10.
