Interesting chip. The Chip Rack shows for the Vegas Doc Holiday which is closed only one chip--a $5 red hat & cane [Paul-Son] chip. I didn't think that the Colorado Doc Holiday had anything other than tokens. But you'll hear from the Coloradoans on that one. I'm not home so don't have the Gaming Table with me to check on other similar chips. Why not send it to Greg and have him scan it--assuming we don't get a read on it.
