if this the time line

74---casino open --76----casino closed----86casino open ---- 88---you start going to casino---97 casino closed.

possible that the starfish was used between 86-88. they could of had 4 roulette tables at the reopening . had a need for more black jack tables and got rid of a roulette table. people could have left with the chips and replaced with other design. refelt the table pulled all chips then change table design .that's just a possability.

64-74 lucayan beach (monte carlo casino) 74 new name change lucayan beach genting. the casino may have changed it's name but still used the old chips and the large key roulettes before the close down .

81 ---tropicana opens in atlantic city---- 9/88 tropicana gets name change tropworld---- 7/96 --tropworld changes back to tropicana. new tropicana roulettes don't show up for 1-2 years .

just my thoughts.
