Old style electrolytic capacitors, do they have any value? If they were removed off some boards, would that increase the grade of the board? i know it would reduce the weight, which in turn decreases overall value by that amount of weight. I always throw them in the Brown board / Low grade bin when they come off while taking stuff apart. If they were worth anything better then low grade at .15 a pound. Any info?

Those plastic wrapped canisters are most likely aluminum foil capacitors. Common as dirt and worth just about as much. I still don't throw them out as I am hoping I can find a local scrapyard that will pay breakage price for them.

The ones to watch for are the tantalum foil capacitors.

They are junk except the white box style one pictured should contain copper. You might be able to find a scrap yard that will take those as transformers or if you are really really bored you can take them apart easily.

Unfortunately they have no value to us.

You really need to check those capacitors on ebay or other places. Rubycon capacitors can go from $1 - $15 depending on the type of capacitor.

Other larger branded capacitors have similar value.

I'll buy it off you if you're gonna get rid of it.

Just an FYI; that post was many years old. I doubt they kept them this long. ;)
But who knows. :)
