My primary focus is Las Vegas $1 chips, including LE's, NCV's and UV marking variations. So far I have about 720.

I also collect
- las vegas $8 chips (and am missing all this year's lucky 8 chips at the moment)
- las vegas chinese lunar year chips (fits in well with $8 chips)
- Australian chips (any and all, which started because Tim Harry told me it was the patriotic thing to do;)
- playable ex casino sets (I have President Casino New Yorkers, Crystal Park, Vineyards, and a few (but not enough) Stardancers and Ritz)
- manufacturer's samples (just started on these)
