If you're interested in authenticity, then you'll want to confirm that a set's chips have been made out of molded clay. Any poker chips that are made out of plastic (or some other compressed material) may look fairly similar, but they will not have the same finish, and they will not have that trademark "clink" whenever you toss them into the pot.
Gambling chips are valuable to a casino for a number of reasons, not the least of which is that a custom-made chip has almost zero value outside a casino. This, of course, minimizes the risk of money being stolen at the tables, and it also means that the customer is liable for any accidental losses that occur after any currency is exchanged.

The most important thing to consider before purchasing any poker chip set is what you plan on using that set for. If you want a set of chips that you can simply keep on a shelf, for example, then your interest should be in finding an inexpensive set that includes at least four different-colored chips, all housed within a case with cylindrical slots for keeping those chips in order.
