I have a Limited Edition Ten Dollar Gaming Token from the McCarran Airport dated 1959 and I am wondering how much it is worth. It is Silver in the center and gold colored around the edges. On oned side it has a plane flying over a car with the words World Endurance Flight Record, and the other side shows an airplane with the words .999 fine silver and Millenium Series G on it. If anyone knows its worth, or has any ideas on how to find out please let me know.
