Why lower grades still matter

XY Black Star Promos has 216 cards listed in the source sample. Even if the top grade creates strong upside, the calculator still needs to test whether PSA 9, PSA 8 or lower outcomes protect the user from overpaying.

Card identity signals

In the visible sample, rarity context includes Rare and Common; where type data is available, cards include Psychic, Lightning, Fire and Water. Illustrator data such as 5ban Graphics, Eske Yoshinob and Megumi Mizutani gives the pages more identity than name and number alone.
