I got both of the Trop Folies Bergere chips in 1995, the one with the single showgirl (N-4504) about a month after the one with the 3 showgirls (N-1303). Both have "35th Anniversary" on the chips. We always list at least one identifying difference in "The Chip Rack". In this case, N-4504 has H&C mold design while N-1303 has a HOUSE (TROPICANA) mold design.
