Will they? It’s not like there are set prices for anything. And it’s not like you can go to the rare set store and choose from the same rare set at different price points - near mint $18k, mint $20k. It’s just not how the hobby works.
How it works is when you get that rare opportunity to buy a grail set, you either pay what he’s asking or you counter. But neither of you are equipped with recent comp sales of varying conditions in different values.
I think minor condition differences are more a thing inside choppers heads than actual market factors.
