Right now I have only $1 and $5 chips. There are $0.50 cent chips (which I have never seen) and $25 chips (which I have no more of right now). I have not seen denominations higher than $25 so don't know if any exist or not.

I infer from the link below that the Casino closed in July 2001. I read that it was open for 4 months, so timing might be approximately April - July 2001.
