Ive recently come across a problem fitting my chips into a pre-cut frame. As I understand it, Nevada chips are 33mm in size. I have a frame Im trying to fill with $25 obs Nevadas. Most fit in but Ive found some too large and some too small, I can accomodate the larger ones but not the smaller ones such as Overland. My question is: does Nevada have a rule as to size and perhaps weight of chips issued to casinos? Thanks for any input! Don Anderson
