This chip is marked as CG 14704 ,here on The Chip Guide.It is marked as being a error chip.
I do not believe that this is an error.
The casino opened in 1994,and this chip is dated 2004. Which would make this a 10th Anniversary chip.
These 3 names (Swan Creek,Black River & Saginaw ),are not location's,but instead the name's of the 3 restaurant's that are inside of the Soaring Eagle Casino.
