Card # 18b
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 sniffed around the sales pile.
  • 3 recorded sales · 1 in the last year · trades only a few times a year · limited-confidence sample.
  • Its last few sales went $7 → $15 → $30 — a clear march higher.
  • Median moved +233% across the window ($7 → $22).
  • Census check: PSA has graded 698 of this card, and only 25.9% come back a 10 — gems fairly readily.
  • Net-net, the momentum points up — real buyers are paying more, more often. Not a promise, just what the garbage is telling us.

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 8% gem (PSA 10) rate on this set's PSA pop - graded pop is self-selected (best copies get submitted), so a random raw likely grades lower. Expected value ~$90 before the $29 PSA fee (fee only - excludes shipping & insurance), ~$61 after, vs a raw copy around $9 (est.). Grading pencils out here, especially if you hit the $467 ten.
