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
Straight from the Garbologist's clipboard:
  • 9 recorded sales · 5 in the last year · trades every few months · moderate-confidence sample.
  • The recent trail reads $24 → $14 → $22 → $15 → $30 — choppy but broadly rangebound.
  • Census check: PSA has graded 506 of this card, and only 5.1% come back a 10 — tough to gem.
  • Net-net, it's holding its ground — steady demand, no fireworks either way.

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.

🧬 Should I slab it?

Worth grading

About a 5% 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 ~$112 before the $49 PSA fee (fee only - excludes shipping & insurance), ~$63 after, vs a raw copy around $10 (est.). Grading pencils out here, especially if you hit the $744 ten.
