Jghilino, that's why I only remove the chips from low grade boards. Every buyer that I've dealt with will buy low grades with or without the chips and pay the same price.

IC chips are what make board attractive, not plated pins. Gold plated pins on motherboards do have only small amount of gold on them comparing to IC chips. Processing is not that complicated but require a lot of time and patience. I would gladly toll refine your IC chips or buy them outright but I am located overseas (Ireland) so all I can do is to advise you on values and help with processing.

It's hard to nail down yields on ICs unless they are all the same.
Ceramic are worth more than the ones made of plastic, they are older and have more PMs and easier for home refiners to process so would bring more per lot.
Are they all ICs are are their proms/eproms also? Any with windows?
Some of the ones that look like they have little gold, actually have fairly good yields of Pd and sometimes Pt and Ag.
ICs increase in value the older they are either as collectable or because PMs were less expensive and they were not too worried about how much they applied in the manufacturing.
If you have ICs, mixed with other chips that look like ICs you may have more valuable chips than you realize. If it has a window, it's an eprom and worth more. CPUs often have gold caps, sometimes on both top and bottom and are of course worth even more in PMs.
I person I purchase material from on a fairly regular basis gave me a 5 gallon bucket of Eproms he had been saving for awhile. None of them had any gold plating to speak of. He asked me if I wanted them, and told me he would give them to me for nothing if I told him what I was able to recover from them. Needless to say I recovered a fair amount of Pd, and ended up giving him part of the return just because it was so good, I felt bad about not. All that glitters is not gold, sometimes it's some other PGM.

At the heart of science is an essential balance between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. -- Carl Sagan
