I could be wrong but to me it looks like a tattoo gun.
FYI: I am by no means an expert and have only seen them on TV before

It is a tatoo gun without the needles, (they go on the right side) and power supply.
and, it's worth well more that $5 if it works.

I don't know what it is either, but I'll give you five bucks for it.
