On Day T-17, found a tiny brass key and thin brass item with N.S.A. stamped on it. ?

Not sure, could be some kind of pickers check/token? What kind of site did you find it at?

"No such animal"? Couldn't resist, could be anything.

“Non Specific Artifact”

I don't see any way to wear it like a necklace, so my guess is that it stands for "No Strings Attached"

Stamp another A on that after the N. Wear it around your neck, and maybe people will think you make space machines ! Nice find, whatever it stands for.
