The keeper is the red/yellow corky. Maybe the moss agate if its in clean condition. Sell the rest in a lot with your other non keepers. cheery pick then sell the bulk!
1 looks to be a Christensen swirl possibly? ..or a modern Jabo? 2,4,6 are Akro Agate corkscrews. 5 is a slag; ...probably Christensen because of the "9" pattern. 3 is a Vitro.
