it depends on the grade, $100 a pound would be lowgrade-midgrade and could be sold to a base rate buyer, ebay or to a specialty escrap buyer/refiner. I have a group of buyers i prefer to sell to, what i do is sort the stuff out by grade and email the pictures to different buyers, youd be amazed at the range of prices you will be offered for the exact same item. Im putting a lot together right now of 10 pounds of single sided solid gold plated boards, will get $100-$120 per pound. I have about 2 pounds of double sided solid plated that will go for $200-$300 per pound. But i have to sell that to an escrap buyer that specializes in high yield boards/trimmings/fingers.
