Binions (the current iteration) has multiple sets of No cash value chips they use. The ones they use in the WSOP events are Bud Jones chips (shown below -stolen from someone's Ebay auction completely without permission for illustration purposes here). They are getting out but not too many.

They also have BJ and Paulson tournament chips for their satellites and daily tourneys and the satellites played for the WSOP. Here is an example from my collection

They have two other sets - an 8-suits hotstamp and a paulson hotstamp set. This is all I've personally seen, there may be others.

In the past they have changed them every couple of years and quite a few have gotten out and show up on Ebay.
