anything of value? or just low grade boards if that? could I mail them in as mixed boards? thanks!

All should be peripheral except the brown board, which is low grade, remove the aluminum heatsinks, and the battery from the top left board
(Of course I could be wrong, lostinlodos has been grading for a long time, so you should wait for him too)

awesome thank you..i was able to separate a few motherboards but came across a lot of miscellaneous boards as well...what can I look for to identify if a board is peripheral?

Exam has it right.
Not enough on the brown board to make midgrade.

Top left remove the battery
Middle right remove the heatsync; it's too large
