A little help with desktop phone boards?

I have done several searches and am not having much luck finding anything out about the boards inside of these phones. They came out of ROLM/Siemens phones manufactured in the late 80's and early 90's. Any help and/or suggestions would be greatly appreciated!

Thanks

What would you grade this board at and should I remove the screen from it?



The following two pictures are of the same board, the contacts inside the buttons appear to be gold (sorry for the blurry picture on the close-up). What would this one be graded as?

Jordan B this is C Jordan
I repair business phones but not that brand. Not all business phones have good boards in them so check them before buying to scrap. The top board should be motherboard or better with the LCD removed. The other board is most likely mid grade. check with someone who buys ewast on this.
If anyone is interested I can make a list of the ones that are good and the ones I know are just low grade.
