Payphone boards

I won the auction with 7 payphones and a bunch of parts. Most of the boxes are marked "good" or "working" so those parts I'm going to try and fleabay. Had a number of boxes that had "bad" on them. Inside was a number of parts including these boards.

Telecom board?

What grade you think about this one?

Few other fun facts. The cases are of course steel. The back of these cards in pictures are mounted on either alum or non-magnetic stainless. Behind one of the stickers is an IC chip with a window. Got to go find the thread I had read on here what they are called. I know they are worth more then normal IC chips (I think). Also have many of these devices with a large spool of copper on it.

The brown ceramic chips with the stickers on them, if they are gold underneath the windows then they are worth around $50/lb. Otherwise they go for same as IC chips. Normal sizes are 9-13g each making them worth $1.00 -1.43 each. Not sure on the boards though, lots of low grade components other than the ic chips. I've never seen those chips on that type of board before though. Those green translucent boards i've never seen graded here before. The first and third rows in the first pic look nice though. Rest are mid to low grade i'd think but a buyer here will soon give you more of an idea.

On pic #2 I was offered 1.80/lb minus shipping from a buyer on this forum......Not sure if that's good or bad

Here's a description of a mid grade board;

A midgrade board is green on both sides and has some ic chips mounted to it but also have heavy items on it as well, such as heat sinks, transformers, large capacitors and other non-precious components.

And the "Also have many of these devices with a large spool of copper on it" is a relay that electronically opens or closes.
