Can someone help me with grading these boards? They are very heavy. The backside of all these boards looks like the picture for “A” The silver that you see on the back is copper.

I would say peripheral low for sure. It really all depends on if you have a local yard or not. For me my local yard their Green board prices are less than peripheral low even with shipping costs, but its very close. If your only option is to ship to board sort just ship it and hope for peripheral high.

^, Peri low for sure, try for Peri high
