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
Straight from the Garbologist's clipboard:
  • 10 recorded sales · 3 in the last year · trades only a few times a year · moderate-confidence sample.
  • Following the trash: $550 → $500 → $400 → $600 → $450 — a clear march higher.
  • Median moved +50% across the window ($333 → $500).
  • Heads up: the last recorded sale ($450 on 2026-05-13) landed 25% 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.
