I would send an email to Chris, but I don't think you are going to get very much for them (including the boards in your other posts)... Do not be surprised if you get peripheral or lower for the ones with no surface mounted devices. All the gold looks nice, but in reality it is an extremely thin flash plating that is a fraction as thick as the layer on regular gold fingers.
Most of the precious metals recovered from e-scrap is in the surface mounted devices. The board itself contains mostly copper and epoxy/fiber filler with only trace amounts of gold.
If you were to take a normal gold finger card and strip it if all its components, you would downgrade it peripheral or worse... essentially that's what you have with those blank boards.
I did notice you had a few with components on the boards... I would expect you to get peripheral at the least for those with an outside chance of getting something better.
I may go down there in the next couple days so I can see what they say (since Chris's reply time can be rather lengthy sometimes). But if you find out before me, please post the verdict as I would be interested in knowing.
Thank you for all that info, we paid 6 cents a pound so if I can make more than that I am happy. I do see that there is gold and yes you are right it is very thin and only on the surface. When I get to the point of selling them I will email someone and find out the best way to go. There is a ton more of these, but they are mostly broken off and in a pile of mess that will take me weeks to separate.
