Older boards not sure of class.

Looks like some boards with little if any e-scrap value.
103/038/006.jpg Low Grade
936.jpg Mid Grade
932/912.jpg Seems to be front and back photos. Midgrade.
As a sidenote. Boardsort may not have any interest in even purchasing those boards. Also. If you are intending to mail those boards. The cost of postage versus weight of boards. I can't see it. I mail exclusively. I do not mail boards like you have.
Looking for experienced e- scraper to comment.

My evaluations are my own opinion

All of these may have a higher value tracing than current circuit boards, or ones where they cake on solder to them. Possibly even silver. Given that and their age the other components may be of better quality (or at least precious metals were cheaper then so low quality may even have some decent pms)

103 would start at midgrade at a minimum, there's gold in the corner and the red toggles have gold legs, depending on the larger switches being dead weight or value adding there's room to easily jump to low peripheral.

038 low peripheral at minimum, all those toggles appear to have gold legs, I'd expect high peripheral though leaving the fingers

006, ICs! but these toggles don't appear to have gold legs (same equipment though so maybe bad picture?) leaning high peripheral here as long as the fingers stay.

936, definitely midgrade unless there's something I missed

923/12, tricky there is gold in the long connectors but not sure about the led sockets. Midgrade would be my starting point, possibly higher depending on those sockets
