Should I be keeping these?

[sys7em]

Hey all,
I am in the process of depopulating some old boards and was wondering, should I be keeping any of these resistors or capacitors? Are they trash? Should I process them or would someone buy them?
Below are some pictures of some of the boards I got along with some of the capacitors/resistors ive removed.

Thanks in advance for your input!

Some of those are tantalum capacitors. Etac buys them.

a nice closeup shot of that plate with everything in it would help. I see some items that remind me of something i read on here.

by the way, those are some nice looking boards

Here's some information on the tantalum cap's:

I believe I also see some silver mica capasitors:

Keep it, collect it, incinerate it one day and you may get out some silver. The resistors f.e. are low yielding silver sources. But it alll adds up.

My take on removing components from boards first it is a lot of hard work. ask what is valuable, " you did that ", then remove only those, " i would say the Blue caps " perhaps tubular tantalum, but you need Leeds, leed length, to be used again, " by some one " i would just remove all stuff, by using a tin lead eluent, " stripper " there are good products that work well on the market. the boards are gravey, you got some good boards. but, quick bottom line
is strip the stuff as quick as you can, perhaps keep the blue ones, for big crush some day. i buy components. but only ones removed with long leeds, " that can be reused " from Thomas, , my take on it. Cheers. again, very nice boards.
