Nike Air Jordan Retro 1 "White/Red/Black" (1994)
Current Price: $960
If $960 seems a tad high for a pair of shoes that went on sale for $20, that's about right. But these are actually a pair of samples, complete with the original stickers on the insoles, which bumps the rarity (and the value) up quite a bit. You won't see these often — it ever again.
