This is the conclusion I had come to long ago but forgot to raise the question. Its a combination of your 2 possibilities based on the following.

Casino opens with two tables in 1995. In 1996 a third table is added and all chips are changed. In 1999 (expansion) two more tables/chips are added.

Which means:

1995: 7 colors - Roulette #1 Blk w/Gold Flame

1995: 7 colors - roulette #2 Blk w/Gold Flame

1996: 7 colors - Blk w/Gold Flame - SHOULD BE DELETED FROM TCR

1996: 7 colors - Blk w/Silver Flame - SHOULD BE DELETED FROM TCR

1999: 7 colors - blk w/Gold Flame - SHOULD READ 1996

1999: 7 colors - blk w/Silver Flame - SHOULD READ 1996

1999: 7 colors - OrngYel Flame

1999: 7 colors - PurpWhite Flame

1996: 7 colors - Silv w/Silver Flame

2000: 7 colors - blk w/Orng Flame

2000: 7 colors - blk w/Silv Flame

2000: 7 colors - OrngYel Flame

2000: 7 colors - PinkWhite Flame

2000: 7 colors - Silv w/Silver Flame
