I have found a large amount of copper cables and wire on my property. My Dad worked for he phone company for 40 years and he dumped all the wire and cable there. Any suggestions on getting the best price? Do I need to sort it, or clean it? I have about a 4 foot deep pile and I am sorting it by whether it has insulation on it or not. I have got a pickup load already and I only got the clean stuff so far. Thanks for any ideas!
