5. Has the style of gold pins that are probably manganese, not gold plated. Same style on MOBOs that currently don't get gold plated anymore from cost cutting. MAYBE Low Per but prob Low/Mid grade
4. Low Per, because the pins are good and the gold fingers are an arrangement I feel would recover better than meta.
3 and 1. Low grade, and possibly might not even want to be purchased because there's no population and it doesn't look like a very heavy Cu bearing PCB(bread board).
2. Low Per, and I'm assuming maybe even High Per; because those chips are SIP packages. Those are actually IC's, In-line packages*. The gold flashings might be enough to push it up too.
EDIT* 1. Is a nice green board, didn't notice the Cu and flashings but it is still only Mid grade. Def will purchase this one though. 3 is still in question, if BS will even purchase it.
