I've gotten a few items that the seller claimed to be NOS and the pictures looked that it could have supported that. When I got them they looked kind of rough to me and sellers always came back with, "well what do you expect, that's 20 years of shelf wear" or something similar. Usually, shipping things back is too much of a hassle, so I end up eating that premium I paid for NOS. I guess my definition of NOS includes a bit of mint or near mint that isn't implied for other people who think that if they put a hub in a drawer with sharp objects that got opened and shut until the decal is half missing and the thing is all scratched up and dinged is still NOS. Sure it was never actually laced to a rim as evidenced by pretty pristine spoke holes, but, at some point, that no longer counts as NOS to me.
