Las Vegas Advisor is still offering the book with the chip. Here's the ad:

We’ve got one of those only-from-LVA deals this week. Richard Wilk's entertaining book, Connected ... Vegas-style: True Tales From the VIP Playground, recounts his meteoric rise to superhost (you may recognize him from the reality show "The Casino") and how he became the "host to the stars," such as the cast of "The Sopranos," major league athletes, WWE wrestlers, and assorted movie stars. The book by itself is a great read, but here’s the special part: There’s a bonus. Every book comes with a special limited-edition Golden Nugget $10 promotional chip. The chips can be played as a matchplay at the Nugget tables (they have an EV of about $4.75), but with Tim and Tom's sale of the casino, these limited-edition chips may have value as a collector's item. And that’s not all. We’ve negotiated a volume deal that allows us to drop the price of Connected ... Vegas-style from $14.95 to $11.95. So there’s the deal, a book and a $10 limited-edition matchplay for $11.95 plus standard shipping rates.

As far as I know, this is the only way to get this chip.
