Turns out the William Hill Sports Book is in both the Ocean Resort Casino and the Tropicana Casino in Atlantic City, NJ and uses the same cards at both locations. The card from there was originally listed under just the Ocean Resort in the guides so that has been updated with the card now listed under William Hill New Jersey with notes under Ocean Resort and Tropicana about the sports book. On the ChipGuide the scans of the card will show up under all three listings.
