Aaron, I just cashed in80 lbs. Of traffic signal boards from the 70's and 80's, and they were amazing!!! I must tell you to turn on the the lights and really take your time researching the ic chips, mainly the removable ice cream sandwich chips. There should be 90% gold finger boards, and if you got the housings, then the aluminum scrap return might actually pay for your entire lot. I hope that is the case. I was stoked to get a few pounds of gold leg ic chips with caps on mine. I hope that is also the case for you. I hope you win altogether, best of luck!
