I went to the scrap yard today and pulled 5 boards with lots of gold plated pins. Three were appox 6" X 14" and two were approx 12" X 14". All had about half of the board populated with pins. The downside is that they all had heavy female connectors on the other side and the man at checkout wanted 20$ per pound!!! Considering the 5 boards weighed 12 lbs I declined and left them at checkout. Unless they were super thick plated I had estimated less than 2 grams yield (uneducted guess) for all of them. Did I do the right thing? The checkout man insisted he could get that price from a refiner when gold was a lot cheaper and wouldn't budge off the 20$/lb. I saw an '81 date stamp on the boards and left out in the elements they had fair moisture saturation.
