Greg is right, Mike, there are hundreds of different old chips, some used for poker, some for roulette. They generally retail from $1 to $10 although there are exceptions. The 'crest and seal' type seem to be popular with some collectors who are otherwise not interested in poker chips, and they have a price range more like $6-$40. Getting Dale's book is the best bet if you have an ongoing interest in these. If you want to scan a few, I'll be glad to look them up. If this isn't possible and you want to send me color copies (or the chips themselves) I'll tell you what I can about them.
