Sorry can't help. Only grades I know are "low grade" and "good." Your boards look good.



I used to try and figure out the specific grade, but now I don't care. When I get a good board, I put it in a box and when the box gets heavy I ship the box to the ewasted guy (cashforcomputerscrap.com) and let him figure out the grade. He knows a lot more than I do, and he knows infinitely more than the buyer at my local e-scrap yard.
