Box of Boards Help with Grading

I picked up a box of boards a few months ago at an auction. I am new to this whole ewaste thing. But for two bucks I figured why not, there was even some computer cables on top. Anyways I'm confused on what I have. I have 3 that I believe are just normal finger boards, some that are finger boards but the fingers are silver, and some that I believe to be telecom? Please take a look at the pictures. The first board all those IC chips are in sockets I assume I should leave them in there

Even in they are all in sockets like in the first board. Figured if there were just a few it wouldn't devalue it but all of them. Guess you learn something new everyday.

I think you did really good! That last board, what was it used for if you know? It looks like the capacitors are all standard aluminum electrolytic types. Based only on their size, but take a good look at the silver color ones. Look for the + sign on the capacitor it self. The board looks to be from the 70's or early 80's. You could have some Tantalum capacitors, a ounce of hermetic or Ag/Ta caps could be worth from $1 to $4.50 a ounce.

I have no idea what it was used for. The box they were all in had IBM on it but it could have been just an extra box.

The 3rd pic the 1st one looks like an old video card the 2nd is modem and the 3rd could be a sound or video. The other ones look telcom check them for ta caps. In the 4th picture check the blue caps i have had a bunch that looked like that and were ta caps. Good pick on the boards.

Sounds like I got the answers I needed. More people can still chime in, Never can learn enough.

Can you read any of the information on the silver looking capacitors?

I did they had a +- sign and the blue ones had just a + sign

The top and bottom cards in the 3rd picture down might have some good resale, I would check ebay. There are either Silver or Tantalum capacitors on the other cards(the Silver colored ones, not the blue ones.
