But it was in New York when this chip was in use. The executive offices in Fairfield, Conn were only set up in 1974. Schenectady, NY was the historic center of the GE Co. with major manufacturing and engineering operations in the area.

My first job out of engineering school was with General Electric in the Syracuse and Auburn NY areas.

GE maintains an archive of information and photography through the GE Hall of History in Schenectady. My guess is you will find the Dunes poker chip in this museum [g].
