Very hard question to answer as all collecters have different "favorates". If I see a chip I like, I try to collect it regardless of denomination. A lot of collecters like to collect from a certain area but you can bet they have some chips from all over the world. Colorado & New Jersery have real nice chips also. I am not an expert by any means---been collecting for about 8 years. Other people will tell you more.
