I wouldn't think so, if they're made of steel, titanium, etc, unless they were to get wet and rust. Left in tight packaging, I can't imagine they'd suffer at all. I'm no chemist, and have not done a stitch of research, but this is what I believe based on my rudimentary knowledge of metal--not specifically metal notions. Needles I found when I bought a 1950s Singer were still good as new.
That said, I wouldn't hoard any more. Go ahead and see what kind of "quilting beast" you actually become in retirement and start by using what you've stored.
