Card # 56
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…

Too Thin To Call
The Garbologist sniffed around the sales pile.
  • Only 2 recorded sales on the books — not enough for a trend without kidding ourselves. The last one changed hands at $150 on 2025-04-26.
  • With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.

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.

Worth grading

About a 44% 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 ~$144 before the $29 PSA fee (fee only - excludes shipping & insurance), ~$115 after, vs a raw copy around $30 (est.). Grading pencils out here, especially if you hit the $220 ten.
