I noticed in the new chips added to the chip Guide, there is an engraved Indian Chief. I was under the impression that generic antique chips were not in the Chip Guide. They are already in an antique guide in the "Other Guides" section of the Chip Guide. All of the codes from those chips are from Dale Seymour's book. There have been many, MANY new codes and variations listed in the last ten years. I suppose the Department of Redundancy Dept. can sort that out. Perhaps, it's better to have information repeated than to not have it at all. The Chip coded PE-HX with four different reverses should probably be listed in the regular Chip Guide. They look like club/personal chips or maybe test chips of some sort.
