I was in the Reef Casino in 1999 and they did have some table games. It was a small dumpy casino at the time but, it is now called the Grand Princess Casino and is VERY nice. Best casino on the island. They didn't just change the name, it is a complete make over. Plenty of table games and a poker room/table as well. I was in the new casino last summer.

As for value, I think the $5 chip is somewhat common amongst Caribbean chip collectors. There is a second version of the $5 chip as well with different colors. The $25 is not as common, but then again there are less $25 chip collectors of the Caribbean.

Hope this helps.
