Photo 1 is a back plane board. I think they pay same as motherboard grade or little higher. They are usualy very thick and heavy. Reason they are thick is the amount of comunication channels running between all those pins. I would put photo 3 in the mid to high grade telecom reagion. $4.50 or s a pound? Photo 4 no idea maybe low to mid grade telecom? Photo 5 pop of heat sinks and sell as finger cards. These are my best guess. I am still learning grades myself but thats what I think.
