What is the dumbest items you've seen someone else sell for scrap?

So I came across 100 or so of these items recently and thought to myself someone may buy these for more than scrap. They're about 4" long with what appears to be gears on each end. I've done some research on them but have come up with absolutely nothing. So I come to pick the brains of the various experts this forum has. I would rather not scrap them but sometimes that's what happens to stuff that falls into a category known as oddball.





That wasn't the title i put in! I'm a bit confused as to why that was put in.
