I shouldn't speak for someone else but I heard a few years ago that Dale Seymour had over 250,000 chips. That is a BIG collection.

I have been collecting for about 10 years and have around 10,000 chips equally divided between roulettes, regular chips and illegal club/UFC chips. I thought that this year at the convention I would have a hard time finding illegal club chips I needed (and could afford) yet came home with around 400 of them.
