They look a little off as the Jumpman is angled to the right on the box and the two XX's are a bit off. I am fairly new to legit-checking KAWS 4's so I may be wrong.
It depends on your size. It seems that sized 9-10.5 are more uncommon and seem to go for 200-300 USD. Other sizes seem to go for 100-200 US. I don't believe there is an official number count on how many shoes were manufactured and sold.
