Peter, I do not know how long you have been on the BB, but if you do an archive search I think you will find the following statements. I am quoting from memory and may not be the exact words.

Collectors of riverboat chips are collecting junk chips.
Indian casino chips are usless.
LE's are worthless.
Old NV in good condition are the only chips worth collecting.

The statements were posted by one of the authors of the "Official" book.
IMO the authors of this book do not deserve the loyalty on any of us.
