While I agree with your guide, there are enough exceptions, that a book would make sense. Just looking at Wisconsin there are some chips that only 200 were made (a 50c blue from Red Cliff) there are some unknown quantity LCV and H&C $2.50s and from the same casino RHC and H&C of the same design $5. Not rare, but unusual.

There were some $10 chips made, that it appears, only two escaped. Or maybe a $25 or $100 from Rainbow, discovered when taking the tables apart. (asking price was too much, so whoever it is that has the two known, still holds them.)

First rack Rainbow Chipco $5 is more common than the $1 Chipco. Don't ask me why, but that's the way it is. I haven't seen a $2.50 in a couple of years. Same goes for some of the other older $2.50s from WI.

After all that, your guide is still pretty accurate across the country for non-Las Vegas, non-AC, non-Colorado, Riverboats and Casinos.

My main interest in an Indian Casino guide would not be values, unless I stumbled onto something more valuable by accident, but for identification and origins.

Janice O'Neal has an excellent list, with discriptions, open and closing dates, when the chips were used. No pictures, no prices, just great information. I'm not sure what states are covered, but it did have WI, MI, MN which were of interest to my collecting. Janice would also be the most qualified and likely person to compile a credible book on mid-states tribal casinos. If it wasn't for her list, I wouldn't even know of some of the older chips that came and went in the first years of Indian Casinos in this area.

(ps how much to you charge for your guide Andy?)
