These aren't very easy to find. @Weckedy has some in his set, but probably isn't selling any. And I've only ever seen one other person with any racks of them, although I don't recall who. If you search for "Christmas set" you might find them. There are probably 10x as many with the blue spots though than green. The green ones were from Pacheco, and nobody really knows what happened to the majority of those chips. Not many ever surfaced.
