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…

Steady
The Garbologist has been digging through this one's trash.
  • 7 recorded sales · 1 in the last year · trades only a few times a year · moderate-confidence sample.
  • Its last few sales went $10 → $43 → $22 → $15 → $22 — choppy but broadly rangebound.
  • Heads up: the last recorded sale ($22 on 2025-08-12) landed 31% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 471 of this card, and only 7.2% come back a 10 — tough to gem.
  • Net-net, it's holding its ground — steady demand, no fireworks either way.

Worth grading

About a 7% 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 ~$118 before the $49 PSA fee (fee only - excludes shipping & insurance), ~$69 after, vs a raw copy around $17 (est.). Grading pencils out here, especially if you hit the $813 ten.
