The truth is that most Las Vegas casinos use chips that you would consider light. There is a general feeling out there that the 11.5 gram chips are the closest to true casino chip weight, but this is simply not true. Others, want to get true casino weight chips, although most of the time they don't really know what that is. Some like heavier chips, like some of the 14 gram sets, because they feel good and substantial and are readily available at good prices.
When someone is looking to invest in a high quality set of poker chips, many times they want to try to get as close to the real thing as possible. There is a lot of confusion, and misinformation out there about the weight of real casino poker chips.
