I don't really see anything that stands out as far as high grade goes. The wire wrap backplane in the first pic has tin plated pins on the back side, low grade. The second backplane looks good as the pins on back are plated, but with the plastic still on the card side, you can't tell if the pins are 100% plated. The backplane #3 is out of a StorageTek Powderhorn control unit. again, most of the pins are only 1/2 plated, low grade. The processors are low yield, fiber type. Around here, there $10.00 per pound. Next photo you have pins pulled from buss & tag connectors. Looking at the color of the pins, I'd say they are newer connectors. Not thick plated like the old IBM's were, low grade. Photo 6 shows connector pins for power supplies to connect to a backplane. Lot of plastic and silver-plated copper, low grade pins. Photo 7, again low grade buss & tag type connectors. Photo 8 is a black piece of plastic. Next is another power supply type of pin, lots of base metals, little gold, low grade. #10 looks to be ribbon wire jumpers. Little gold in them as just the tips are plated, low grade.
So to sum it up, I think the best stuff on the whole page would be the 2nd backplane. I would pull the plastic sockets off the pins and list the boards on e-bay. They will bring good money. Be sure to tell the weight of the board and the # of pins on each board. As far as the rest of the boards, throw them in with your motherboards and get your $2.40 a pound. The rest of the stuff (and we have no idea how much you have) might do well on e-bay as well, but I doubt it.
