2018 Garbage Pail Kids Series 1 80's Gross Bears 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.
