Definitely some CAC's (Christensen Agate Company) in the group. Those are your blue/red, green/yellow, red/yellow, and black/yellow...although a few of them could be Akro Agate Company. Hard to tell from the pics. The most collectible is the blue/red/yellow CAC. Condition is important to value.
A handful of other interesting mid-century machinemade marbles. And a bunch of catseyes.
There is also a handmade clay and an "Indian" in the mix. Have fun
