Antique Coca Cola glasses.

I have 4 of these and am too embarrassed to show the other 2 which I believe are now worthless. I started to wash these with super hot water,dish soap and a scrubber sponge thing. When I got to the 3rd one see pics I noticed the label,decal was coming off and that the first 2 were pretty shot. Then I noticed the waviness of the glass and realized they were much older than I thought. Should I throw the other 2 away? What should I have done differently? How old are these? I feel sick about this whole thing. Where can I go to find a fair value?

Thanks!
