Now I know that some folks on this board relish reading the various confrontations that pop up here occassionally.... and others wish they would go away. I shouldn't talk, as I've been involved in my share of them. Just wanted to attempt to cool down the termperatures a bit. Paul; I don't have a definition for you of what a crest & seal chip is, but I know one when I see one..... and I have a few in my collection. Maybe Doc Meyers would like to chime in to give a more definitive explanation to your question. I don't have Dale Seymour's book in front of me, but I think he may have a included a page or two on the subject in his book of antique poker chips. You might want to consider borrowing a book or two from the club library if you aren't intererested in purchasing one. Regards.....
