Some Peltier Rainbos, Vitro Cat's Eyes, West Virginia Swirls, maybe some other Vitros, some Marble Kings. A lot of vintage. Some modern. Most American. Some foreign.
I think these are commons.. So I wouldn't pay much for them.
The boulder sized ones with green stripes are the most interesting to me. If they are Peltier Rainbos then that's cool. You don't see a lot of large Rainbos.
