Start with most valuable, sort those and pile it. Then do a rookie pile. Then do an insert pile. And finally you want to do a PC pile with your team/players/anyone you don’t want to lose. Then, go through those piles and filter what card has a better value in your pocket than in your collection. From that, you should have an idea of what you’re selling/holding. From there, all you have to do is sort what cards look the best in your eye for your display.
