We never take bids. Every bid happens on ComicConnect, under their terms.

Same book, same gradeshowcase #27Same title, issue and grade across sources — different physical copies. Not the same slab. For one specific slab's history use cert provenance. Mixed premium basis: ComicConnect sales before 2023 are shown without a buyer's premium (the rate's start date is unverified) while later ones include 15%. Medians here mix both.

Under review — this key may be merging different things.
