Plans for destroying discontinued chips must now be approved by the board, and they are far less unusual than they were before Regulation 12. The casino must also post a discontinuation notice where the chips can be redeemed twice a week in two different Nevada newspapers with general circulation during that 120-day period. For a period of 120 days, the establishment must offer redemption of the discontinued chip at the casino or another recognized site. When it comes to retiring a set of chips, there are also precise rules that casinos must follow. When stacked with various denominations, the chip’s denomination must be distinguishable via black and white closed caption from the side. Regulation 12 also specifies the exact size of chips, as well as the information that must be displayed on them, such as the denomination, the location of the business, and the chip’s maker. Casinos must submit a sketch of the new chip’s design, including security features, for approval. The Nevada Gaming Commission’s Regulation 12 governs the approval of new chip designs, as well as the disposal of the ones they replace. From time to time, Las Vegas casinos release fresh chip designs to combat counterfeiting, modify branding, and guarantee that their internal money does not get too “grubby.” So, what happens when an older chip is replaced by a newer model? It’s handled differently today (and far less interestingly) than it was in the past.
