Old telecom boards I scored

I just got in 1000 of these 5.2 lbs a piece. Any idea on gold content. Are they high-grade? They are old GTD5 old line cards.

i see a lot of relays- they can have Ag or Ag/Pd contacts and nice fingers

Nice load Todd.Are they all the same? Is there anything on the bottoms?
I see a few IC's,and as Sucho pointed out,the relays may have some good PM yields.
But the "5.2lbs each" scares me.Is there a lot of steel on them?

Yes lots of steel and plastic. I'm pricing at mid-grade.

I have processed many boards that look much like that one. Are there gold contacts on each side of the board? If there are I typically get 3.5 to 4 grams of gold per pound of trimmed fingers. Good find.
