Here's another big set of boards I'd appreciate feedback on. This is a representative sampling of the ~150lb of this stuff we got recently.

There's a big range in how populated each item is, so my big questions are;

- What do you you think a ballpark per-pound price ought to be on the whole load? I'm guessing $4-$7, but there's a lot here I'm not familiar with.

- Some of the backing/printing looks like silver or tin. Can anyone tell me what that is, and does it much affect the value?

- Should I bother removing the IC chips that are socketed, or would that greatly de-value the boards?

And I've already found some 'mercury-wetted-contact' items I'll need to hazmat, but if anyone sees anything else of note/concern, please let me know. Any and all advice is appreciated.

Thanks very much.
