Remove copper from a PCB without dissolving it?


I have a bunch of old PCBs laying around from various electronic projects, things I took apart and re-purposed, etc...Seeing as copper is roughly $0.25 per ounce, I would like to remove the copper from these PCBs, and sell it to a local coin shop that buys various scrap metals. I plan on sanding the solder mask off first, but after that, I don't know how to remove the copper from the fiberglass. Maybe just electroplate it onto another piece of copper? Please give me suggestions, thanks!

You can't electroplate it off, your best bet is to etch it off, and plate out of solution, but its going to cost a lot more than 25 c /oz to do it at your kind of scale.
