A Jazz neck with a Precision label...from the factory...I'd keep it for that reason alone.
Not only would I keep it, I would try to get Fender to come off with some paper work saying it is authentic and a factory mistake, it's the least they could do for shipping this out like this in the first place, I would think that might add value in the future. I dunno, there's probably some sucker out there that'd pay few extra dollars for something like this (maybe even me...LOL!!)
