Card # 8a
Garbage Pail Kids
TCA Value iTCAxis 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…

Cooling Off
The Garbologist sniffed around the sales pile.
  • 60 recorded sales · 22 in the last year · trades about once a month · high-confidence sample.
  • The recent trail reads $200 → $115 → $140 → $64 → $114 — ran up to a peak of $200, then cooled back off.
  • Median moved -20% across the window ($138 → $132).
  • Census check: PSA has graded 1,977 of this card, and only 1.7% come back a 10 — a genuine condition rarity.
  • 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.

Worth grading

About a 2% 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 ~$823 before the $599 PSA fee (fee only - excludes shipping & insurance), ~$224 after, vs a raw copy around $77 (est.). Grading pencils out here, especially if you hit the $12,240 ten.
