Also, if I cut them out of PCB instead of desolder them, do I lose just a bit of copper each time or buyers can seriously be displeased that I did that?
Think there are different definitions in play. Have seen a few times where people put something less than 50% copper and call it #2. #2 officially has to be less than 1.5% contaminated and that 1.5% can't be, for example, steel. But local yard shorthand can mean everything from Cu breakage to actual #2.
