You're going to want to remove the faceplates and separate the boards (cut the ribbon cables off) otherwise it's going to drop the value.
The largest board on the set of three I believe can make low telco grade once you get the above off.
The middle sized board; can you get a better photo of the two silver boxes with NEC on them? Make sure all labeling is visible even if you take multiple pics to get it (Do Not Remove them)
The smallest board looks high telco.
The second board looks like it has a fair bit of gold on the board compared to the third board which does not. Both have a lot of heatsinks, those look like they may be copper/brass; are they?
