Got through most of my piles and found some boards I had set aside because I wasn't sure if they really fit neatly into a category.
Left bottom, brown board has a good IC population. Left top, the gold pins and contacts and a couple ICs. Middle board I didn't think much of but there are silver teeth on three sides. Right board IC population.

Left, gold??? Middle, peripheral? Right bottom, gold teeth but basically blank board otherwise... Right middle, peripheral? Right top, was really just curious about the black component with the gold legs.

Left bottom, the ICs, gold teeth, red/brown color? Left top, ICs and gold pins/teeth. Right bottom, thought low telco but maybe too much extraneous weight? Right top, a little damaged but I think from a smart thermostat?
