Need help grading these boards please

These came out of an old Intel computer and I'm curious how they would be graded.

First picture is the MB, is it more than just a high grade MB? Lots of IC's on it.

Second picture is a board with two cpu's on it, one says 486 (cracked it when I removed the heat sink). I'm thinking it has to be better than slot processor price due to the 2 ceramic cpu's on it. It weighs around .4 lbs. and the cpu's alone should be worth $10 or so.

Third picture is some finger boards with lots of IC's, would they be telecom or?



Thanks for your help, I'm trying to learn all I can and it's rare to find these old boards.
