Charles -

I forgot about that one and it's probably where the chip came from.
Although, I was there in 1989 and it was Treasure Island Casino and that was 14 years ago.
I don't know what year it became the Atlantis.
As you said, none of them say St. Maarten on them.
I don't know if the casino is still open or under a different name.

Here are the $1 and $5 chips from that casino.
