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…

Trending Up
The Garbologist popped the lid on this card.
  • 3 recorded sales · 0 in the last year · trades only a few times a year · limited-confidence sample.
  • The recent trail reads $1 → $26 → $12 — a clear march higher.
  • Median moved +1804% across the window ($1 → $19).
  • Heads up: the last recorded sale ($12 on 2023-03-20) landed 32% below our current value — weigh it as a single data point.
  • Census check: PSA has graded 503 of this card, and only 6.8% come back a 10 — tough to gem.
  • Net-net, the momentum points up — real buyers are paying more, more often. Not a promise, just what the garbage is telling us.

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 ~$99 before the $49 PSA fee (fee only - excludes shipping & insurance), ~$50 after, vs a raw copy around $8 (est.). Grading pencils out here, especially if you hit the $600 ten.
