Here is my take on those:
-First pic is an Air Card that Boardsort pays higher than telecom however there is no price list for it but if you have a bunch send a message to Chris to give you an accurate quote. If this is the only piece you can just toss with you gold finger cards.
-Second pic is a gold finger card. It can go for large socket motherboad but because of the gold fingers you can get a higher grade.
-Third pic looks either Telecom or Green/Brown Fiber with Metal. If the board is the processor of a like a Mac then it is a Green/Brown Fiber with Metal
-Fourth pic looks like a No Pin Processor. Check the first picture to the left in this link:
http://boardsort.com/cpg15x/thumbnails.php?album=24-Fifth pic to the left is a Mid-Grade or Low Grade to me. Although it is a BackPlance it does not have any gold plating. The pic to the right is Peripheral.
-Sixth pic: the two backplanes to the left I would grade them mid or Low grade since they show no gold platting. The upper right board is Peripheral and the lower right board may go for Telecom. At worst is Peripheral
