The figure is the same ungated market median the range on this page uses: every seller found. Certificate tier still ranks the cards. The purity gate is written and off, so this is not a tested-sellers-only series.
We never charge for knowledge. No vendor has a say in what a page says. Sellers are ranked by the certificate they publish, then by price. Every seller, graded · Laboratories named · How this is counted
