I have a couple dozen of these boards that came out of very large DirecTV equipment (i.e., not residential receiver boxes). I believe part of the transmission systems. They are fairly sparse with respect to chips, etc, but there's a lot of gold surface area. What would these grade as? High peripheral? Seem too sparse to go as telecom. Thanks!

High peripheral at the least, maybe low telecom. But not higher. The gold looks prettier than what it is worth, it is basically gold colored paint from what I have read around on the Boardsort forums.
