Re: borrowing The Chip Rack....
I have the 10th & 11th versions of TCR and 2nd & 3rd versions of "US Casino Chip Guide (Campiglia and Wells)" and also the 2nd Edition of Luke Rapley's "A Guide to the Casino Chips of MI, MN, ND, SD and WI" ... Since my main collecting interests are Nevada and the north central states, esp South Dakota, these catalogues are great to have but can be expensive to purchase for those just starting out in the chip collecting hobby.
Since I'm already here talking about chip guides, for those who collect from the north central states (mentioned above), I do recommend Luke Rapley's guide. It is very informative with photos and well worth the cost.
