The first chip on the left is the correct chip and courtesy of the ChipGuide.
The second chip on the right was one I harvested many years ago from a Poker Tournament and its missing 2 letters on the end of "Tournament" and "Group".
Color differences are probably just from the scanners.
I actually harvested the whole set over the course of a few visits.
Once I realized I had an odd chip I wanted to get back and see if I could get the other one, but the Atlantis ran into some financial problems from what I heard and then got hammered by Hurricane Irma in 2017. Then it changed to "The Starz" but used Atlantis chips and to the best of my knowledge it never did reopen.
