2023 Garbage Pail Kids Intergoolactic Mayhem Kosmic Krasher Price Guide

How the set trend is measured: only real recorded PSA sales count — never estimates. For each card that sold recently and also sold around the start of the period (30 days, 90 days or a year ago), we compare its typical price now with its own typical price then; the set figure is the middle of those per-card changes, so one unusual auction cannot swing it. A number is shown only when at least 10 cards sold in both periods and they clearly point one way (the likely range of the middle change stays above or below zero); otherwise it says no clear direction yet. Sales counts, dollar volume and the median sale use the same clean sales. “Value backed by real sales” is the share of this set’s total guide value that rests on each card’s own recorded sales rather than an estimate.

“Change” is this card’s typical price now against its own typical price that long ago (SETPCT_1105: its last 30 / 45 / 60 / 60 days vs the same span 30 days / 90 days / 180 days / a year back) — the very figures the set number above is the middle of. “Last sale” and “sale before it” are that card’s own two most recent recorded sales (we keep two years), and “last vs prior” compares those two prices. A dash means the card did not sell in both periods; we never fill one in. Real recorded sales only — no estimates.
