Found these while helping a friend clean up any ideas? thanks!
I was going to Pull the IC chips off as well as black Heat sink.(how can you tell if its copper )

If you plan on selling them to boardsort I would leave the ic chips on. Removing them will downgrade the board. There are a few different types there. Mostly peripheral with a few exceptions. The heat sink is most likely aluminum. But if you want to be sure. File off the black color in one spot and it will be either reddish copper color or silvery aluminum color underneath.

When zoomed on pic only (clicking )
The bottom centre one is midgrade. Rest should be peripheral most likely.
The board on top... you can remove the square ics from the sockets without issue (i always do) but leave the rest alone.
That heataink /does/.need to be removed for peripheral. You /should/ be safe removing the tiny gold finger. It's not anywhere large enough for finger card class and doesn't affect the board's population at all.

Test the sink with a file or a flat head screwdriver. Simply gouge it if golden or orange you have copper (or an alloy) if silver you have aluminium and if a powdery grey that crumbles or splinters magnesium.
All three materials are common with server boards.

Thank you very much for the help! I have about 10-15 of these boards.
so glad to know what they are
