In Hollywwod, FL there are two separate casino operations with similar names operated by the Seminole Indians. One uses the Hard Rock brand name and one does not. The non-Hard Rock casino has just issued new chips, this according to Tommy Leggio, a CC>CC member.

I am not familiar with any NIS in that area, but Tommy advises that he can provide chips for $2.50 and $4, respectively (including shipping). Tommy is available via email at:

These appear to be Chipco, satin finish chips.
