Re: 2009 new chip releases
For Nevada there is a list of approved gaming chips and tokens that comes out each month. I don't have the link right now, but it should be pretty easy to find on the chip board or on google. That can give you all the chips that were approved in the last year, although some were approved and didn't actually make it to the tables yet.
Another option is to join up with a new release service on the chip board. There are a few collectors in the Nevada region who pick up new chips when the release announcements hit. I don't know for sure but some names that come to mind are Ricky Pushkin, Andy Hughes (he may or may not be starting up again) and Chuck Smorse. THey may have a log of last years chips, and can also help with getting new chips this year as they come out
