I found 4 of the green tail and 5 of the purple tail. These are the three best of each.
These are not easy to find. Rated T in the chip rack($350-$399). Prices are as follows and include shipping(in a bubble mailer) and insurance. I would entertain trades for similar 50cent chips that I need.
Top green tail-$300
Middle green tail-$175
Bottom green tail-$175
Top purple tail-$225
Middle purple tail-$225
Bottom purple tail-$175

Thanks very much for looking. Email if interested.
