1. Asian cat's eye. Common style. Modern. If there's any value, it comes with the large size.

5. Maybe Vitro cage style cat's eye.
6. Asian cage style cat's eye.
7. ?
8. Appears to have an oily finish. Modern.
9. I think vintage. Not seeing enough of the seams to be able to guess maker.
10. ?
11. Maybe West Virginia Swirl. If so, then vintage.
12. Is this light-ish or heavy-ish. If light, then probably clay, though could be a ceramic with color worn off. If heavy, then maybe stone. Though old, no particular value. One name for a single-colored clay marble is "commie" ... because they were so common.
13. Hmmmm ... probably vintage. Two or three companies it could be. Marble King, Vitro, Akro. Maybe I should be able to say which one, but it's too early in the morning.
