I'm just an amateur when it comes to chip collecting. I was totally overwhelmed by the sizes of the collections displayed and talked about at the CCA convention. My collection is only about 650 chips, but they are mine, and I like them!

I collect: Casinos that I have visited,
Current Las Vegas
Older Vegas casinos that have a significant history (and that I can afford).
Any chip that I think is attractive and catches my eye

(I know that's kind of vague, but that's the best I can do at the moment.)
