I mainly collect coins, so I regularly go to the big shows in Florida, Michigan, and the Chicago area. I will be at the Long Beach show for the first time later this week (that one happened to coincide with a scheduled trip to Disneyland).

I don't find a lot of good chips. When I find them, they are common and overpriced, and fantasy chips are mixed in. I agree coins hows are worthwhile, though - especially if they are free or cheap to enter.
