John,
BOTH The Gaming Table AND the Campiglia/Wells Price Guide are invaluable references.

If you really have to choose just one, I'd recommend that you go to the club website, to the references section, and look at the books available in our library. I'm sure both of those are available...check them out and decide which works best for you.

The Gaming Table is more a casino guide than a chip guide....though it does mention molds used for some casinos. The Campiglia/Wells guide has hundreds of chips pictured, for several gaming jurisdictions.

The Gaming Table edition that's available for sale, right now, is the second version. The authors released a limited amount of "audit editions" for the third version, but those are sold out.
