Really cool old boards(pics inside)

I have no idea how to look these chips up, the gold ceramic ones. I'm not sure were to even go to, to find out. I was suggested to try out here.

here are the pictures of what I have, what do you all think? Should I scrap these or try to harvest the components?

Well I also tried reaching out to some people on reddit and they helped me out a bit! i'm still not sure if I should try to sell the components individually or try to take them off the board and recycle them into their metals. I'd hate to destroy something that is actually rare

Leave them on the board and sell the boards whole. De-soldering them greatly reduces the value to a collector. A gold scrapper would not care but a collector - well personally I dislike de-soldered chips. These are nice looking boards!

These boards are probably from a telephone exchange or some other communications device - maybe a military radio. The company GTE stands fro General Telephone & Electronics Corporation so that might help you in your research
