There have been a couple of addendums too. I don't think there will be another published by Dale Seymour. I don't know of anyone who is thinking of publishing an up to date version. Robert "Smitty" Smith and a couple of other people have put an updated version on the internet. It is as up to date as the chips that were coded at this years convention are there. I think you can view this updated version at antiquepokerchips.com
