No idea where you could get the actual prop chips. I know there's a big trade in movie props, but I've never gotten into them myself so I can't tell you how best to go about looking for something specific.
I happened to run across an
eBay listing for a chip and a card that were props used on the 2003 NBC show "Las Vegas" featuring the fictional casino "The Montecito". I snapped it up but haven't seen any other listings like it since then. See

The prop chips, though, were made by putting labels on blank chips called "Spirit Molds". Spirit Molds were made in a variety of colors and spot patterns; the ones shown in the Chip Guide aren't very common and would probably be hard to find. EXCEPT, though, for the blue-spotted red chip used for the $5, which you can buy blanks for right now if you hurry before they go out of stock again:

So if you're not looking for the
actual props and just want to replicate them, you could reproduce the $5 very easily. I don't know of any way to get the others, though; I've never seen those particular blank chips before, neither in person nor even in pictures.
