I just bought this controller at a flea market for 3 dollars. The Xbox button is completely white, so at first I thought it must be a fake. Looking at the back it says Xbox360 controller Krypton, so I looked that up and it turns out those are prototype controllers. I found one on eBay in very good condition that got sold for 115 dollars. Mine is noticeably yellowed, the joysticks feel weird, like there's dirt underneath preventing them from moving properly and the RB button is unresponsive, so it's probably not worth much. I'm gonna open it up and clean it to see if I can fix those issues. Even if I don't get the RB button working it was well worth the price, I'm just curious if they're rare.
