Don has explained very well the two variations of this chip. See the picture below. It's the top center two chips. The problem with price guides is that the first version without the break is one I have never seen. Seven dollars is way out of line with that one. I'd happily pay $20. If you can get Dale Seymour's book on antiques you'll find it a treasure of information. I look for something in my copy almost every day. One thing, Dale's book is in B&W. The photo project I show here, is color version several collectors and myself had worked on for some time. It has actual color photos of the new chips we have. It is for our own enjoyment and reference.
