I know there's not a lot for low grade boards but when you have a lot them when there's time I try and clean them up as I go along. Can you please tell me if you see anything else that I need to remove from any of these pictures? Also can I get rid of them when they are broken? Sometimes cleaning things off of them they tend to break apart a little bit. Thank you!

They are all low grade so anything you can remove is probably worth more at a local scrap yard.

i remove every ic chip from those boards, they go to boardsort. and rf connectors are brass. som copper coils easey to take apart. 3 leg transistors with copper back, remove the plastic and you have copper #2 and some aluminum heatsin... the rest goes with the low grade board
