If I understand your question correctly, there are 12 years of commemorative / tournament chips issued by the club.

We've had 13 annual poker tournaments, but we used casino-provided chips the first year. Starting in 2000 (the 2nd annual tournament), the club issued a 5-piece set when we played at the Excalibur. A 5-piece --- or more recently, 4-piece -- set has been issued each year since. When we added the BJ tournaments in 2003, both tournaments have been reflected on the chips. The last few years, the chips have been strictly commemorative (not used in the actual tournaments). Before that, the chips were used in the tournaments.

You can pick up some of the previous year chips from the club's promotion director. See insert in most club magazines, or use the pdf linked here from the club website:
