I have a collection of Disney World dollars that are in sequence and in excellent condition. My mother had her own television show in Ohio and we were invited to tour Disney World before it opened. My father received these Disney dollars to spend once the park opened. These dollars were put away and never used. I have photographs from our visit to the park, showing everything still under construction, and images of my mother, being met by a Disney World representative for the tour of the park. The serial numbers are extremely low and in sequence.
