When I received my two sets of Casino of the Sun chips today from Jim Follis (big thanks!)I noticed what is either a variation or error in the $1 chip. The chips have the name of the casino around the outside edge. When you look at the Casino Del Sol side on 5 of my 6 chips the edge is readable. On one $1 chip the edge printing is upside down. Is this just a variation or an error? If it is a variation then I need the same variations for the $2 and $5 chips also. Any help out there?
