I have the The Chip Rack and The Chip Guide as resource books. I understand that they should be used as guides (not written in stone) in pricing chips. But what about chips, current and obsolete, from states that are not included in these two books. How does a collector get an approx. value of these other chips? Is there written material or other resourses that can be used to obtain a baseline value for chips from states that are not in either of the two books?
