A call to the casino cage at LVH informed us that the change is set to take place March 30. From what we can gather, although the name change took place as scheduled on January 3, 2012, following the loss of the Las Vegas Hilton’s franchise agreement to use the Hilton brand, with the outdoor signage coming down and website changing over, the chips won’t change out until the end of March.
We then sent LVH a message on Twitter, and they responded that the notice is likely to be posted starting mid-March.
For those of you who have no clue what we're talking about, under Nevada State Gaming Control Board Regulation 12.070, if a casino is going to discontinue its chips, whether because of closure, or a name change, or any other reason, it’s obliged to give fair warning (at least 120 days) to allow holders of its chips to redeem them.
The notice of the discontinuance of the chips or tokens and the redemption times and locations must be posted prominently in the casino and published in at least two newspapers of general circulation in Nevada at least twice during each week of the redemption period (check the Legal Announcements section in the "Business" section of the Las Vegas Review-Journal, for example.) In Nevada, once the time’s up, however, your chips lose all face value, other than as collector's items.
