The drop at Caesar’s World poker rooms as well as MGM poker rooms is now $6. The poker rooms that have a promo (bonus for a royal flush, etc) take an additional $2. So the $2 chip would make sense, although I vote for a $6 chip. That has been done in some CA and FL card rooms. Closest in Nevada is the Peppermill in Wendover, which uses $4 and $2 drop chips at the same time!
