I have about 10 or so of these pin boards. They are from a General Electric "jig machine" according to the customer. My first thought is that these look like the ones Barren buys for 14.00 per pound but I am not sure. My scrap yard guy got a 71% Au reading with the XRF gun. I know they can be misleading with plated material. Any ideas?

Edit- They are about 18" by 12" boards if that helps.
