@farmerman,
clean copper is over $4 a pound here, last I looked.
definitely worth cleaning first. (removing all other metals and chunks o' crud)
I don't get a lot, but there is a small pile north of the shop. I get more brass than copper. but I don't work it. just whoever calls.
I am having signs made to put on my truck saying I buy junk cars for cash.
one call that pays off covers the signs with room to spare. might as well make all the miles I drive pay for something. advertising is expensive...
I believe I saw where pennies are worth 3+ cents as copper. (I save all mine. everything else gets turned into paper once a month or as needed in emergencies)
