Quote:
you mean like a paper shredder?
As it turns out, a cross-cutting paper shredder found in one's house can pretty much exactly replicate this effect, both with copper and plated zinc cents.

Added: If my math is correct then with roughly 156 g of metal, you have the result of somewhere between 50 and 62 individual cents' worth of metal there. Ignoring wear and tear on the paper shredder, this seems like a way to make a quick 4x-5x return.
