I can't even guess but it's gotta eclipse Doncic so we are realistically going to see $500+ on release which makes my brain hurt. I'm wondering were the base will be. I'm hoping they settle around $15 a couple months in that way I won't mind picking up one or 2 but not interested if they are doubling that.
With Zion you are probably better off busting wax in the beginning because it's going to take a lot more than 2 months for his cards to shed some value - especially if he's still rehabbing. If he's playing and going nuts, they may never drop.
19-120 NBA Hobby Boxes $420-440 USD now, so any good RC silver from those will be priced around there, say your Deandre Hunter, Eric Paschall types, I would think Ja Morant, Rui H, Herro and Zion will be around $600-800 USD mark.
The game is to guess who rookie of the year will be, Zion still favourite in some US blogs. Hopefully his knee holds up, he is a big unit.
I think I will still collect and hold my longer term silver rookies (players that I like) and then look for those future prices.
