The frames are metallic sand and black. And as said, they're Pro M Frames (there are no generations of Pro frames).
The lenses are both RX carrier, and the clear is trashed if that's a crack radiating to the nose from the left lens insert. If they're cracked there I'd wager they're cracked in the frame.
The clear lens also looks a little short and is missing a few features of the Slash lenses. I'd say it's either a custom/prototype sports lens, a special RX size, or the Slash in RX came without all the same features of the normal lenses.
RX lenses aren't worth much unless you know the prescription they're for. I don't think the insert can be removed, and I doubt it'll fit into a machine like that to be reground. So a collector may want it, that's all.
Frames in good shape go for what Doc said, $50-60. More for a rarer colorway, less if the rubber is bad, etc.
